Hi Greg, I think I've found and fixed the problem. I've but a new linux version of mri_convert here: ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_convert Can you test it out to see if it works? doug

i am trying to run tracula on a large number of subjects, tracula dies quicklyin -prep stage when mri_convert tries to copy/rename the diffusion data, the error actually comes from the data read function. the data is already in .nii format
the error is 'unsupported slice timing pattern 5' this is diffusion data that is already in .nii format so the slice timing information is irrelevant, no slice timing correction is done on diffusion data, but the info was obviously encoded in the nifti header.
what do i need to do to get this data to load, go edit the .nii header and 'remove' this info. i tried with the fsledithd function and just setting the 5 to 0 does not work, then i just get a 'read error' with no other information.
this data is from a 1.5T siemens mobile scanner so the snr will be a little lower and the bval = 800 is lower so it is just the data that could use the helping hand of the spatial priors to find the tracts. i can run 500 of these if i can get this fixed, incarcerated psychopaths so an important data set.
thank you
Greg
