Hi,

I’m running the following code - it runs through without error but it doesn’t write the output in the output file.

FiberTractMeasurements --outputfile $outputfolder/FiberMeasurements/$filename/$hemisphere --inputdirectory $outputfolder/AppendClusters/'OutliersPerSubject_'$filename/$hemisphere -i Fibers_File_Folder --separator Tab -f Column_Hierarchy

#2

I just realized that the script doesn’t work properly when the parent directory does not exist. I just created the parent directory and the code is running successfully. I think the code should be modified to either give an error message or create the directory if it does not exist.

#3

Fixed here. From the next nightly version, it should raise an error.

I don’t think there is a good way to check/create intermediate paths before opening a file in the current C++ version we are using (without adding a new library dependency edit: actually I guess we could use vtksys, but the second point still applies), and in any case, doing so without warning might be unwelcome in some circumstances.

Thanks for the report.
