I apologize for being late (I just want to finalize this thread). The error was produced even after resaving the bvecs spreadsheet in openoffice. The issue was solved after setting both bvals and bvecs manually using nano. --- Regards, Alex

Hello Anastasia!

Thank you very much for your response! My bvecs and bvals were created by saving excel spreadsheet as a tab delimited file on mac. I reformated my bvecs manually using "nano" and reran the preprocessing. Unfortunately, it exited with the same error. I'm providing you my reformated bvecs...

I believe that the problem is not in reading of decimals, because running this step with "fake" bvecs of 1s and 0s (test_bvecs.txt) produces the same output with zeros, and everything seems to be ok

with

the tutorial dataset... What would you suggest?
