StatsCircularMeans

puglie12 — Fri, 17 May 2013 07:56:27 -0700

Hello, I am a relatively new IGOR user and I need to use the StatsCircularMeans function to find the mean of some wind direction data. I am struggling to understand how to perform this analysis (such as how to create a two column wave). Any help or guidance on how to use the StatsCircularMean function would be greatly appreciated.

Gizmo wave capacity?

elirosen — Fri, 17 May 2013 11:42:28 -0700

I am creating 3D arrays of images that get large in a hurry. So much so that it appears I cannot, in fact, display orthoslices in Gizmo ("Wave Too Large to Display in Gizmo.").

What is the maximum wave size that Gizmo can handle? I can't seem to find this info through the Gizmo Help .ipf.

Additionally, I'm curious whether the Gizmo window can be resized to reflect x,y,z scaling from SetScale?

Many thanks,

Eli

text wave font

schne643 — Thu, 16 May 2013 23:18:23 -0700

I would like to make a plot with x-axis labels that contain greek letters (for example the labels would be δ-methyl, β-ethyl, and so on). I have tried to do this via the following method: create the plot with two numerical waves (the x=axis is sort of dummy wave with values of 1, 2, 3, 4,.....), create a text wave in a table that contains the desired x-axis labels, and in the plot select the "user ticks from waves" to link the labels to the data points. I am stuck at this point, however because I do not know how to change the font of part of text in a text wave (or if it is even possible to change the font of a text wave without changing the the default font setting). Is there a solution to this problem or a different way to obtain the desired plot?

Working with large datasets

tooprock — Mon, 06 May 2013 06:45:54 -0700

Dear All,

I have been working on a data analysis routine which reads data from *.csv files, perform several statistical calculations on it and generates some useful easy to understand scientific outputs. One part of the routine handles 3D data containing many zeros and/or NANs. At the end I replace zeros with NANs and exclude NANs by using WaveTransform function. However the data is so large that my computer doesn't have enough memory to keep hundreds of 3D waves with thousends of entries. Could someone have a look at the code and give some programming clues which may solve this issue? I know it seems complicated and confusing. I would be appreciate for any helpful comment.

Cheers,
Emre

How to make first derivative and second derivative of a 2D line

lihao — Wed, 15 May 2013 08:06:36 -0700

I meet a big problem to treat the date. Is there anyone please tell me how to make first derivative and second derivative of 2D line?

SetVar and active setvar proc functions

daggaz — Mon, 13 May 2013 01:52:12 -0700

So I made a slider and it contains an event-driven if statement in the corresponding proc function, which executes code when you move the slider.

I tried to do the same thing with a SetVar, but I cant even get it to run a print statement. Ive used SetVar to initiate variables before in a user-interface, but I used a second function to read all those variable and then feed them into the main function. This time, I would just like the proc function to run some code if the user pushes the up/down arrows or enters a new value into the field. Is it possible or have I misunderstood the functionality here?

function setvar_proc(setvar_z, z, varStr, varName) :setVariableControl
 
   string setvar_z // name of my control
   variable z  // the variable being manipulated
   string varStr  // not sure what this is for
   string varName // again, not entirely sure what you would use this for
 
   do a whole bunch of stuff like load some new images in my fancy panels based on the new z value
   print "Oh Igor, why don't you love me anymore?"
 
end

My button shows up with the correct variable value inside (and moving the slider keyed to the same variable changes this value, as well the opposite, changing the value here moves my slider), but nothing else happens. Igor refuses to print even.

Saving graphs with large images in mixed bitmap/vector format

agarttha — Wed, 15 May 2013 02:37:41 -0700

I have a graph with a large image. I want to save/export the graph keeping the axes, labels, and all annotations as vector art, but the image data as a PNG bitmap with a resolution I can specify. The PDF and EMF export formats should be capable of producing mixed bitmap/vector data. However the Igor Pro PDF and EMF export produce only vector output, which makes huge, uneditable files since the images are treated as collections of rectangles instead of bitmaps. If I save everything in PNG format, the axes and labels are not vectorial but the file size is small and manageable. I am using Igor Pro 6.3.

Should this go to the wish list or is there a workaround to produce mixed bitmap/vector output?

Thanks

Extracting values from text waves

Catalin B. — Mon, 13 May 2013 09:11:01 -0700

Hello all,

I am fairly new in using IGOR Pro. What I want to obtain is: from a 2D text wave I want to extract 2 numbers and store them in 2 variables so I can use them later in various calculations.

The attached image is an example. From this one I want to obtain the numeric values corresponding to pict_details[2][4] and pict_details[11][4].

Does anyone know how to do this?

Thank you.

Data browser plots and graphing layers.

aqshaw — Tue, 14 May 2013 11:32:08 -0700

Hello

I'm working with some data that I have stored in a 3D wave. Most of the is energy profiles in x and y coordinates with a third parameter being the orientation of the object. As the third parameter is not z, I did not feel a volume plot would be appropriate so have been using image plots. I find this is suitable but I would like an easier way of browsing between my layers than using the Modify Image command to select the plane.

I noticed when I load my wave in the data browser it shows me a set of stacked image plots it calls a "3D box," that lets me browse through the layers with the arrow key.

Would someone be able to tell me how I could plot this sort of graph for myself? Also, if possible, I would also like to index the layers by their angle values rather than trying to remember what Layer #7 mean.

Thank you for your help.

Embed an existing graph in an existing graph

gravityhomer — Mon, 13 May 2013 14:55:45 -0700

So I know how to embed a new graph inside of an existing graph. You just open the tools and then right click on the graph and create a new graph inside. But I would like to take a graph that I have already created (with many curve fits and such applied) and embed it into another graph as an inset. I could remake the graph, but it seems like there should be an easier way to do this.

Thanks!

some help with this small iteration procedure

daviddoji — Mon, 13 May 2013 06:42:01 -0700

I have a wave (that it´s a loop) and I would like to subtract the upper line points from the bottom line points. In fact, I´m interested only in certain range of my wave (this is why I choose the points i=3616 for the upper line and ii=16070 for the bottom line).
But I don´t know how to make the iterations! I mean the first value should be the point 3616 minus the point 16070, the next point should be 3615 minus 16071, and so on. The final point should be the last pair of values (that´s why I have put i>235, because for i=234 there is no more points in the wave.)
This points should be stored in a new wave with exactly the same number of points that iterations have been made.
I think that the problem in my procedure is in the definition of the for loop. As you can see, I don´t have any idea about programming, but I try to learn by myself :)

#pragma rtGlobals=3		// Use modern global access method and strict wave access.
Function/D iteration ()
Wave wave
variable i, ii
i=3616
ii=16070
make/O/N=??? new_wave
for (i=3616;i>235;i-=1)
	new_wave=wave[i]-wave[ii]
	i -=1
	ii+=1
endfor
end

Attached you´ll find the graph with the wave.

Button Appearance

Quinten — Mon, 13 May 2013 00:54:20 -0700

Hi everyone,

I apologize if this has already been addressed. I have a small issue with user created buttons. For some reason buttons I create have the appearance of custom controls rather than the Mac style buttons. Every now and then a button turns out with the right appearance but I find it almost impossible to reproduce. I tried all the options in the appearance option for buttons but nothing did the trick. Also, I changed the native GUI settings in Igor's Misc settings. Has anyone had this problem?

Cheers,
Constantin

displaying slices from a 3D wave

daggaz — Fri, 10 May 2013 05:19:42 -0700

I have 3D waves and so far to display a z-slice ive been using the rather bulky

duplicate/O/R=[][][z] 3D_wave 2D_wave
newimage 2D_wave

which seems obtuse considering the data already exists, but I cant seem to quickly call up the slice in any other way. What is the correct method here? Eventually I want to make a function which loads the image and uses a slider to move thru them (half way there)..

Help browser not showing

notwhatucallanatural — Mon, 13 May 2013 05:44:52 -0700

My help browser doesn't appear any more, either from the menu help/igor help browser, or the keyboard shortcut cmd+/. I think this has been the case for a few days now.

The context menu help all looks to be there if I right click on a key word, but I can't browse e.g. command help. If I scatter the open windows using a hot corner, then a window label for the help shows up as open, but there is no window associated with it.

Any ideas why this might be the case? I've restarted Igor, and the computer.

plot label and tick

oipunx — Fri, 10 May 2013 17:39:57 -0700

Hello,

I'm new to Igor and I'm having a hard time trying to make the x-axis label on my plot to display engineering unit like 1E-6, 5 E-5, 1E-4, etc. I have looked at the "ticks and grids" tab and tried to switch between "engineering" and "scientific" but it cant get it to display how I wanted. It always shows 100x10^-6 etc... Also the x-y ticks are overlapping at the corner with my manual range setting, is there anyway to make it not overlap? I have attached an example here.

Thank you

Printing multiple layouts into one single PDF file

eesyliu — Thu, 09 May 2013 21:14:39 -0700

I want to know if it is possible to print, say, 12 layouts into one single PDF file.

I can print layout to PDF at the command line by setting the PDF printer as default printer but how I can print more than one layout into one single PDF?

I have lots of data and need to general reports automatically. If this can be done then I can avoid copying the layout and paste them into one Word file to make a report.

Thanks.

I can´t change the orientation of a layout and neither embedded graphics on it

daviddoji — Thu, 21 Mar 2013 07:38:42 -0700

I´m using the demo version of Igor 6.31. I was using Igor 5.05.
In this new version, when I create a layout (Windows>New Layout>Do it), Igor generates a portrait layout. If I need to change it from portrait to landscape, I go to File>Page setup for this layout.
But Igor says: The page setup failed. Do you want to replace the place setup with a default setup?
Whatever I press (yes or no), Igor gives an error: The operation could not be completed because Windows OS error of an unknown nature (Windows OS error code: 10). In using Windows 7 64 bits Home edition

But the funny point is that if I choose from the command line: Layout/S /P=Landscape, Igor creates a landscape layout.

Another problem is that I can´t embedded graphics in the layout. When I insert a graph in a layout and right-clic over it and try to convert graph to embedded, Igor says: Can´t put controls in a subgraph.

Thanks in advance.

highlighting specific frequencies in waves

epiphenom — Thu, 09 May 2013 08:49:06 -0700

If I have a wave that contains multiple frequencies , how can I highlight where in the data a specific range of frequencies occur? For example, if the data has frequencies between 1 and 500Hz but I am interested in finding where frequencies from 3-5 Hz are present, how would one go about doing this? The duration of the wave is about a minute long.

Why Igor Pro 6.22A is slower than Igor Pro 6.1 ?

feifeihanyu — Fri, 10 May 2013 05:28:33 -0700

Hello all,

Does someone also have the same feeling that the new version 6.2 is slower than previous version after an update when it calculate the same data? For example I made a procedure to integrate a small range for each wave, say from the point 55 to the point 80 of wave0, wave1, wave2... to form new wave.
The same procedure in different version costs big difference in version 6.2 and previous version such as 6.1.
for example 5 second in version 6.1 but 30 second in version 6.22.

Could somebody tell me the reason? How to improve it in new version? or just keep using the old version?

Any suggestion is welcome. thank you.

using waveexists and creating the non-existant wave

daggaz — Thu, 09 May 2013 02:53:29 -0700

Igor doesn't like me.

wave testwave //have to declare it or waveexists wont work
if (waveexists(testwave) == 0 )
...make/o/d/n=1 testwave
endif

I cant seem to do this, as the two wave references are overlapping. Is there a way?

Also just in general, some way to check for the existence of data before running a section of a user defined function. Purpose being that said function will create certain data on the first running, but subsequent passes would then skip this part. The check has to be permanent after the function has finished running, which is why I tried with a wave here..

shade under curves

Hello,

I have made a plot of 3 different curves and Im trying to shade the area under the curves where the horizontal line intersect the other 2 curves. It should be shaded so that if it's under the larger curve, it has a different pattern than the smaller curve. I have an example of what it should look like in the attached jpeg file. I have read the manual but couldnt figure out how to do this so any help would be greatly appreciated.

Thank you.

Using if endif statement checking odd or even number of data in wave.

Hello,

I am doing some FFT repetitively for some data file and I want the script to check if the number of data points is even (a must for FFT) or not. If it is odd, then delete one data points from all wave to make it even.

Variable NOD=DimSize(wave0,0)
Variable REMAIN=mod(NOD,2)
 
if (REMAIN 1==0)
 
DeletePoints NOD-1,1, wave0,wave1,wave2,wave3,wave4,wave5,wave6,wave7
 
endif

I used the above code to detect the modulus. If the number of data is odd, modulus equals to 1 then one data point will be deleted from all waves.

However, when I run this in front of all other codes, Igor prompts me "expected wave, variable name...." when it comes to the "if" code.

So, I want to ask if it is not allowed to run "if endif" directly in command line without putting them into a function?

Or, what is the simplest way to achieve that? (make all waves to even number of data points for FFT. Thanks.

Gizmo commands should appear in the command window

Hi,

it would be very helpful, to see the Gizmo commands appear in the command window. Because, then I can directly use them for scripting.
