Loadwave question

Share icon

Hello,
I am trying to load a file (.dat) that has 11 columns. The first column is time (00:00:00), the following columns are numbers (with decimals) separated by tabs.
Igor loads the 11 columns, but it is not separating the data in the columns. I end up with a matrix of 11 columns all containing the same values, which appears to be that of the first column. I have tried altering the "loadwave/v=", but nothing seems to work for now.

I would be grateful for all suggestions.
Thanks

Here is the code that I am using.


Function LoadLog()	// Loads Log data

// Prompts to select folder into which data is loaded
String PathToFldr="",CtrlName="",PromptStr="Select folder to load Log data into:",CurrentFldr=getdatafolder(1)	// variables for Browse4Folder
Browse4Folder(PathToFldr,CtrlName,PromptStr,CurrentFldr)	// prompts user to select an experiment

// Get folder with data in it
	NewPath/M="Select folder containing Log data:"/O/Q pathname	// prompts user to select path to data folder
	PathInfo pathname
// Abort if cancel is pressed
	If(V_flag==0)		
	Abort "proceedure cancelled"	
	EndIf
// Make matrix for Log data
	Make/o/n=(0,11) LogDataMatrix
// Strings and Variables 
Variable numfolders,n, subdirs, numfiles, filenum, refnum	// variables
String folderlist, filename, name, currentfolder			//    strings
// Counts number of files in folder			
NumFiles=ItemsInList(IndexedFile(pathname,-1,".dat")) 								// # files in folder	, specify extensions e.g. ".txt"
	
	For(filenum=0;filenum<numfiles;filenum+=1) // loops through each file name	
		filename=s_path+StringFromList(filenum,IndexedFile(pathname,-1,".dat"))	// get full path to data file	, specify extensions e.g. ".txt"
		If(Stringmatch(FileName,"*Log*")==1)
			Open /R/P=pathname/Z refNum as filename	// open
			FStatus refNum	// check there is data in file
				If(V_logEOF>10)	// specify minimum file size to load e.g. >10bytes
					Load_Log_File(filename, refnum)	// calls function to load file	// unique function for specific file format
					Wave  Temp_LogDataMatrix0	
					//	add loaded waves to loaded data
					InsertPoints DimSize(LogDataMatrix,0),DimSize(Temp_LogDataMatrix0,0), LogDataMatrix
					LogDataMatrix[DimSize(LogDataMatrix,0)-DimSize(Temp_LogDataMatrix0,0),*][]=Temp_LogDataMatrix0[p-DimSize(LogDataMatrix,0)+DimSize(Temp_LogDataMatrix0,0)][q]
					currentfolder=GetDataFolder(1)			// root folder for experiment	
				Endif	// end data to folder allocation
		EndIf
		
	EndFor			// end loop through files of a dp
	
	Close/A 			// close open files
		
	Killwaves Temp_LogDataMatrix0
//	Do additional analytsis on Log data
	//ProcessLog()	// adds a time wave

End

Function Load_Log_File(filename, refnum)	// load single Log file
	String filename
	Variable refnum
	print "Loading: " + filename
	loadwave/v={"/t","",1,1}/q/a/n=Temp_LogDataMatrix/m/o/j/k=1/l={0,0,0,0,0} filename	// loads Log data as a matrix
End



Your /V flag has forward slash. It should be a backslash. Backslash-t represents tab.

If that is not the solution then please zip the file or a representative part of it that illustrates the problem and attach the zip file to a post.
