Load All Matrix Files From Folder

 

Menu "Load Waves"
	"Load All .dat Matrix Files From Folder", LoadAllMatrixFilesFromFolder("", ".dat", 0)
End

//	LoadAllMatrixFilesFromFolder(pathName, extension, makePlots)
//	This function loads each matrix file in a given file folder into Igor.
//	pathName is the name of an Igor symbolic path or "" to get a dialog.
//	The name of each matrix file is assumed to end with the specified file name extension.
//	The output wave name is the file name less the extension.
//	If makePlots is true, a new image plot is created for each matrix.
//
//	NOTE: You may need to change the LoadWave command to fit your file format.
//	Use Data->Load Waves->Load Waves to find the right command and then adjust the LoadWave command below.

Function LoadAllMatrixFilesFromFolder(pathName, extension, makePlots)

It is the very procedure I am now seeking. My matrix files (.spe) are generated by Princeton Instruments Camera.
I understand that I have to load .spe files instead of .dat by using this useful procedure "Load All .dat Matrix Files From Folder", and I also noticed that there was a procedure "Winspec.ipf" or "SpeLoader.ipf" available.It can help load .spe files. http://www.igorexchange.com/node/2756
My question here is how to combine these two together to get a new procedure to directly load .spe files. Many thanks.


Make some changes before you have to.
