what's your command-line? It's probably looking for the acq paraemeters. If you can't get this fixed, then you'll just have to supply the bvalues and bvects on the command-line.

Dear Thomas and all:

When I processed the DTI data with dt_recon command, I encountered the same problem as the following one you posted in last year. Would you please tell me how to solve the problem?

My Freesurfer version is 4.3.0,and MRI data is from Siemens Trio 3T. Attachment is my dwi-infodump.dat. Someone else has an idea?

Thanks

In the third stage, the glmfit, the process stops after giving the ERROR message: cannot extract sWiPMemBlock.alFree[8] from .../ dwi-infodump.dat And indeed, there is no visible entry of this in dthat dwi-infodump.dat. Somebody has an idea? Thanks for help! Thomas/
