// This example shows a panel popup menu to list data folders from the root level
// It excludes the Packages folder from the list
// The New selection allows you to create a new data folder from the root level
// NOTE: this does NOT set the location to the folder ... see the comments for details
 
Function MakePanel()
 
	// make a sample panel
	// ... (use your own values here)
 
	NewPanel/W=(10,10,50,50)
 
	// ..

Very early version.
Farthest Point clustering appears to work, KMeans is broken at this point.

Example Use

Adds one menu item per trace to the GraphMarquee menu. Selecting one sets only that trace's values which lie inside the marquee to NaN. Both Y vs X and waveform traces are supported.

No undo is provided.

#pragma rtGlobals=1		// Use modern global access method.
 
#include <Axis Utilities>
 
Menu "GraphMarquee", dynamic
	CommandPerTrace(),/Q, SetMarqueedValuesToNaN()
End
 
Function/S CommandPerTrace()
 
	String menuList=""
	String traceList=TraceNameList("",";",1+4)	// visible traces
	Variable i, n= ItemsInList(traceList)
	for(i=0; i<n; i+= 1)

The following code requires that you have the genetic optimisation package installed (http://www.igorexchange.com/project/gencurvefit).
The snippet uses Monte Carlo resampling to estimate fit uncertainties and parameter correlations for a given set of data and a fit function. (see, for example http://www.casaxps.com/help_manual/error_analysis.htm)

Place a cursor on a graph with a bunch of waves. This function will generate a table with a list of Y values corresponding to the X value of the cursor.

Function GetAllYValues()
	if(!strlen(CsrInfo(A)))
		return -1 // No cursor on the display.  
	endif
	Variable xx=xcsr(A)
	String traces=TraceNameList("",";",1)
	Variable i,numTraces=ItemsInList(traces)
	Make /o/n=(numTraces) YVals
	Make /o/T/n=(numTraces) TraceNames
	for(i=0;i<numTraces;i+=1)
		String trace=StringFromList(i,traces)
		Wave Wav=TraceNameToWaveRef("",trace)
		YVals[i]=Wav(xx)
		TraceNames[i]=trace

sending gmail with IGOR

From experimenting with the XOP's SOCKIT and base64 (available on IGORexchange), I've found how to send email from IGOR, using the SMTP protocol. It works quite well, although there is one catch. You have to install a program called Stunnel (http://www.stunnel.org/). They have windows binaries available there, and it's easy to install the mac version (./configure, make, sudo make install). There is a config file which one has to get the hang of, but it's not that difficult.

Development of an IGOR installer/package manager

This snippet is designed to act as a discussion place for an IGOR installer/package manager. Each (zipped) package should probably have a manifest of what it contains, so the installer has information on what the dependencies are, and how the package should be installed.

<?xml version="1.0"?>
<package name="SLIM" version="1.0" igorversion="504" location="User Procedures" platform="ALL" igorprocedures="FALSE" igorextensions="FALSE">
    <!-- A folder called SLIM would be created in /User Procedures.  All the content in the zip file would be copied into this folder-->
