[Freesurfer] Troubleshooting for error - neither NIfTI-1 qform or sform are valid

2016-03-20 Thread Reema Jayakar
Hello FS list subscribers, Is there a way to manually feed FS with NIfTI-1 qform or sform information? Or correctly add this information to the original .nii files? My sense of the problem is that there is a problem with the header information in my .nii files and FS cannot tell what is anterior,

Hi Freesurfer Community, I am running mri_cvs_register for the spatial normalization and it seems to work very nicely on my set of DTI data in subjects with substantial atrophy. However, I can't seem to find the file combined_tocvs_avg35_elreg_afteraseg-norm.m3z, however, I have

what do you mean by "adding" an oblique angle? If you mean acquiring the data obliquely you should be fine as long as the voxels are close to 1mm isotropic. cheers Bruce On Sun, 20 Mar 2016, Dr Sampada Sinha wrote: > Dear freesurfer experts, > Does adding an oblique angle during coronal or

Re: [Freesurfer] [freesurfer] XL defect correction?

2016-03-20 Thread Bruce Fischl
Hi Jacky the first step is to look at the output of the processing (if it finished) and see if it looks good. If so, you don't have to worry about it. The very large defects are difficult to correct (or take prohibitively long), so should be checked, but they certainly can be corrected
