Need to extract numeric data from a string of ascii

cdbass — Fri, 21 Nov 2008 10:58:04 -0600

I running a monte carlo program that generates ascii data files in multielement lines. Below is a typical example of one of the line:

0.17758E+01 -0.14488E+01 -0.41742E+00 0.85527E+00 -0.47925E-01 -0.51596E+00 0.65037E-05 0.10000E+01 0.69302E+02

I don't have much control over the output format for this data string, except that I have the option of writing the file in binary, but I'm not ready to make that leap yet.

I would like to read in the line and extract each numeric value. I'm fairly new at igor, and I'm having difficulties getting the string functions to do what I want of them. Useful help or advice would be appreciated :)

Programmatically creating waves

Cory K — Fri, 14 Nov 2008 15:34:20 -0600

I am brand new at writing macros (in Igor), so I'm trying to figure stuff out as I go.
One piece of code that I am having trouble with is programmatically creating waves.
In my procedure, heres what I have so far:

Make/N=200 'WaveA','WaveB','WaveC'..... etc
Prompt xWave, "Enter wave for x values : "
Prompt yWave, "Enter wave for y values: "
DOPrompt "Enter x and y waves", xWave, yWave

Is this correct for picking out two of the created waves, so later in the macro I can graph the two?
Also, is it possible to provide a list of the created waves within the prompt so the user can just pick 2 out?

Thanks,
Cory

Skip loaded columns

Cory K — Wed, 19 Nov 2008 18:50:57 -0600

I am reading in tab-delimited text files using:
LoadWave

Are there any flags I can add to skip columns.
For example if I have columns 0,1,2,3,4,5,6,7,8

But I only want to read in 0,1,4,5,6
What flag would I add?

Joystick XOP IGOR.6.10.x-0.2

AlanSaul — Thu, 20 Nov 2008 10:44:35 -0600

This minor update fixes a relatively major issue. The previous version would fail if the user switched out of the Igor application. This version should continue to run if Igor is running in the background.

Please send bug reports to Alan Saul via alan@adale.org.

Plotting only every Nth point

kevin — Wed, 19 Nov 2008 14:19:16 -0600

I'm plotting data as yWave vs. xWave. There are simply too many points displayed. I'd like to only plot every, say, 10th point. But I don't want to delete any of the data.

Also, I use several different yWaves---something like yWave1, yWave2, etc---plotted against the same xWave, so I don't want to have to change the values of xWave.

Thanks,
Kevin

Multiply array by X

Skargaemer — Fri, 14 Nov 2008 12:20:48 -0600

Hi,

I'm not too familiar with IGOR syntax, how would I take a given array and multiply the whole thing by some constant?

Is this close?:
Duplicate wave1, wave2
wave2 = wave1 * 10
Display wave2

Thanks

Force multipeak fitting

yqgao — Mon, 10 Nov 2008 16:32:55 -0600

Hi there, I am new to this program, here we have written a program to calculate peak area of a series spectra in one file ,for example, wave0 to wave 8000, to construct one intensity image, , while we found that there are two peaks so close that general fitting can not recognize these two peaks as one, we can force fit the specific peak range into two peaks, can any one can tell me how to do batch fitting so that we needn't to do so one by one ?
Thanks

Rudimentary Binary File Reader

Fitting Multiple Curves With Multiple Functions

maxxcw — Sun, 09 Nov 2008 22:42:42 -0600

Here's my problem in principle:

I wish to fit one set of data Energy(x) with the equation a*x+b. At the same time I wish to fit a completely different set of data Charge(x) with the curve a*x^2+b, where a and b are the same in both fits. Is Igor able to fit both of these curves simultaneously by minimizing the summed error from each fit?

Thanks

Multipeak Fit with original negative peaks?

garrison — Mon, 10 Nov 2008 03:54:30 -0600

Dear all,

I am new to Igor Pro and but found it is powerful for signal process. I would like to decompose some characteristic peaks from an experimental measurement. I think the MultiPeak Fit function of Igor Pro should do the job. After several days of trying, I still can't get it works correctly. For example, although it could fit the total curve nicely, but the decomposition, ie. the individual peaks, is not correct.

The experimental data is attached. Could any expert please advice how to utilize MultiPeak Fit and solve the current fit that I can use it an an example to solve many of other measurements.

Thank you very much for your kind help.

Sum of two Gaussians

English_Lab — Tue, 11 Nov 2008 09:22:44 -0600

I wrote a program that will open up a file and fit the data to a gaussian peak. Some of the new data we're collecting has 2 peaks and I would like to know how to fit a gaussian to each peak. Each of these files contains a large amount of frames, so I want it to be automatic. I already have the code in place to fit a gaussian to each frame and load the coefficients into a separate wave for storage. I just need to know how to code for the 2 gaussian fits. Thanks.

FuncFit Error Flag?

leandract — Mon, 02 Jun 2008 13:12:38 -0500

I am writing a macro that runs through a number of files and fits them to a number of user-defined functions. This all works great except when the function returns an error of

**** Singular matrix error during curve fitting ****

which I know means that the equation has too many parameters and one is ill defined. (I'm fitting single exponentials versus double exponentials).

Unfortunately, this singular matrix error crashes my whole macro, when what I'd really like it to do is to generate an error message (that I can redirect somewhere), and continue with the next fit in the macro. It seems like there should be a flag whose status I can check before the macro crashes so that I can skip over the crash part.
Is this making sense?

Thanks,
-Karen f.

Creating waves of arbitrary data

lizhb — Wed, 05 Nov 2008 17:49:07 -0600

I know how to import data, but I cannot figure out how to create waves of arbitrary data inside Igor using command line functions. For example, if I want to make a wave with the values 0 5 3 -2, how do I do this? Is there a way to create a wave like this, where the values are not a function of the index? I know how to do this by using the GUI to edit the values in a table, but I want to implement this via command line functions, so I can do it in my procedures.

Defining a Graph using XML

jjweimer — Mon, 20 Aug 2007 19:55:15 -0500

I am curious about what would be best to define a graph in XML. I am not talking about SVG, which is a way to draw a graph. I am instead talking about an XML database that defines the characteristics of the graph, for example ...


plain
    1pt

    black

    off

    off

    ...
    ...

Before I invent something like this for SpXZeigR as a "preference" type file format that thereafter has only limited use, I thought I would try to find an equivalent that is already in use. I've found this reference as a start. Does anyone have any other suggestions or references?

Layout- Arrange window order

patarroyo — Wed, 05 Nov 2008 13:56:26 -0600

Whenever I want to arrange graphs on a layout, I first create the layout and then arrange. I don't use the dialog by itself; instead I send the command to the clipboard where I manually rearrange my graphs so that they appear in the order I desire on the layout. Is there a way to do this within the dialog? Or is my way the only viable workaround?

Transform Axes Canned Transformations

In a different forum was posted thoughts about Transform Axes as ...

...Perhaps I should add some canned Arrhenius transformation function.

I think the following two canned transformations for temperature would be useful:

b) 1/K -> oC: (1/x) - 273.15

BTW, a factor of 1000 is used to adjust the 1/K scale to be in inverse milli-Kelvin (which can also be done using the proper escape codes in the axis label).

Looking for an IGOR Programmer

kmjacobs — Thu, 30 Oct 2008 12:40:31 -0500

I am looking for someone to make slight minor modifications to a Procedure written by Jeremy Bergsman a few years ago. The purpose of the procedure is detection of epileptiform activity (although it could also be used to detect other kinds of activity). We need to add a moving baseline to the detection using filtered data. I know programmers prefer to start from scratch with their own program, but this is already a very nice module. It just needs this one thing - and then there are a couple more things that would be optionally added.
The procedure currently has FFT as an optional detection method. The calculation of the FFT slows down the automated mode, so we would like the option to turn off the calculation/display of the FFT when we are not using it for detection.

Finally, we would like - perhaps even as a separate procedure/module - so this could be started from scratch - a way to output FFT data. We have to thing a little bit more about this - how we would like the output, etc.

I have the means to pay someone to do this programming.

If for some reason you would prefer to view it as a collaboration in order to get your name on a publication, that is also an option.

Please email me at kmjacobs@vcu.edu if you are interested.

Clementine, package for modeling decay kinetics using MEM and Least square fitting IGOR.6.03.x-1.1

Clementine, package for modeling decay kinetics using MEM and Least square fitting

ilavsky — Thu, 30 Oct 2008 10:27:57 -0500

Clementine was developed to model decay kinetics processes using either maximum entropy (MEM, included) or least square fitting. The math of analysis (decay times are "tau") is :
MEM: signal(time) = FlatOffset + sum (P(Tau) * exp(- time/tau))
LSQF: signal(time) = FlatOffset + sum (P(Tau) * exp(- (time+TimeShift)/tau))
The package will :
MEM : Generate the distribution of P(Tau) values using Maximum Entropy method over user defined number of bins in tau (log-spaced)
LSQF : Model (and least square fit) sum of for up to 5 different P(tau), TimeShift, and tau combinations. Both P(tau) and tau can be fitted.

The code loosely follows following manuscripts:
Zs. Ablonczy , A. Lukacs , E. Papp, Application of the maximum entropy method to absorption kinetic rate processes, Biophysical Chemistry 104 (2003) 249–258
and
A. K. LIVESEY AND J. C. BROCHON , ANALYZING THE DISTRIBUTION OF DECAY CONSTANTS IN PULSE-FLUORIMETRY USING THE MAXIMUM ENTROPY METHOD, BIOPHYSICAL JOURNAL VOLUME 52 (1987), pg. 693-706.

The package consists of :
Load_Clementine.ipf > this file should be in (or linked to) "Igor Procedures"
DecayModeling_Load.ipf > this file should be in (or linked to)"User Procedures/Clementine"
DecayModeling_GUI.ipf > this file should be in (or linked to) "User Procedures/Clementine"

This will load the necessary procedure files in Igor, compile them and add in the "Macros" menu command "MEM Decay fitting".
Selecting command "MEM Decay fitting" from macros menu will open main control window.
For more details, please, read included help file (accessible by button from main control window).
*********************************************************
Data input
There are various data types Clementine can use:

a. one signal wave with x-scaling in seconds - with or without errors wave.
This is raw data from instrument which measures in fixed data intervals the signal. Such data are not properly spaced for MEM analysis. They need to be rebinned to log-time scaling. Check the check box "Rebin the data". If you have these data, you can also use Instrument response function.

b. two waves (signal/time)
In this case you have signal and associated time for each point. If you need to, you can still rebin the data on log scale. But you cannot use instrument response function...

c. Three waves (signal/time/errors)
In this case you have three waves - signal, error for signal, and times. You cannot use instrument response function, but you can rebin the data, if necessary.

Modify mirror axis

Hej!

I have a problem with my mirror axis. So normally it displays the same range and values as the original axis. But I want to display the mirrored x-axis computed as: mirrored x-axis = 1000/(X-axis)-273.15

So, I want to put diverse temperature back to T(°C) on the mirrored x-axis without having T(°C) data.
Is there a simple way to do this in Igor?
An example of a plot with the normal mirror axis is attached.

Cheers,
Jan
