Hi Stefano - I'm sorry that you're frustrated. Do you mean that you arranged the bvecs as 3 columns (not 3 rows) and are still getting the same error?

Hi Anastasia,
I'm frustrated because I'm checking to resolve this problem anywhere but the error is the same. Can it depend from interaction between fs and new iMAC version (Mountain Lion)? Thanks,
Stefano

Hi Stefano - Are the original bvecs (that you specify in your configuration file) arranged in 3 rows or 3 columns?

bvals conversion is ok. What's happen? Why are there an error about conversion to FSL format?
Thank you very much, I really appreciate your patience.
