Load n files from a directory

Hi All,

I would like to load a serie of binary images and assign the name of the file each. Reading the forum I found a function and I modified it:
Quote:

Function load()

NewPath myPath
String name,list=IndexedFile(myPath, -1, ".dat")

Variable i,numFiles=ItemsInList(list,";")

for(i=0;i<numFiles;i+=1)
name=StringFromList(i,list)
GBLoadWave/O/T={16,16}/S=393/W=1/P=myPath name
//ImageLoad/T=TIFF/P=myPath name
endfor
End

I use the comand GBLoadWave but I don't know how I can use a variable (i) or a string (name) like a wave name.

Thanks,

MatLey
GBLoadWave creates two local variables:
S_waveNames -- semicolon separated list of names of loaded waves
S_fileName -- name of file loaded (such as "file1.dat")

You can use these to get a reference to the loaded wave and rename it to the same name as the file. See modifications to your function.

Function load()
    NewPath myPath
    String name,list=IndexedFile(myPath, -1, ".dat")
    String LoadedWaveName
    String FileName
    Variable i,numFiles=ItemsInList(list,";")
   
    for(i=0;i<numFiles;i+=1)
        name=StringFromList(i,list)
        GBLoadWave/O/T={16,16}/S=393/W=1/P=myPath name
        LoadedWaveName = StringFromList(0,S_waveNames)  //name assigned to image by GBLoadWave
        FileName = RemoveEnding(S_fileName, ".dat") // name of file loaded minus ".dat" extension
        Wave w = $LoadedWaveName    //get reference to wave loaded by GBLoadWave
        Rename w, $FileName //rename the loaded wave to file name
        //ImageLoad/T=TIFF/P=myPath name
    endfor
End


The "$" operator seems to be what you were looking for. Type: DisplayHelpTopic "Converting a String into a Reference Using $" into the command line to see more about it.
