I am running into a tracula error very early in the preprocessing steps.  I have data that was already somewhat preprocessed (reconstruction, eddy correction and magnetic field inhomogeneity correction) that I'm trying to use as an input.  I have turned off those steps in the tracula configuration file.  Tracula seems to find these files and starts making a few of the dwi output files in the subject's freesurfer/dmri folder.  However, it then says something about not having the correct "frames" and it can't find the file dwi_frames.nii.gz.  I'm not sure what this error is referring to.  I attempted to run the same subject's data from their raw dicoms instead of the slightly-preprocessed file and also ran into errors.  If it makes a difference, the subject had recon-all performed with freesurfer version 5.0 and I am now using version 5.3.  Perhaps the subject is missing some necessary recon-all output that is only created with 5.3?  Any advice?  

Thanks,

Mike Datko
