Hi Anri - What text editor did you use to create the configuration file? It looks like the last line (which specifies the b-value file) has no end-of-line, and so that line is not executed, hence the failure to find the b-value file. Can you please press "enter" at the end of that line, so that you move to the next line, then save the configuration file and try again?

Dear TRACULA experts

Hello.
I am running TRACULA, but it exited an error very early in pre-processing.
My data is not a format in DICOM but .nii, does this cause the error?
I set the dcmlist to .nii file (in attachment).

Could anyone help me?
This is the error log and I attached the configuration file.
