Hi Ritesh

do you know how those .mgz files were generated? It looks like they were created using a buggy version. You can try setting:

setenv FS_SKIP_TAGS 1

then rerunning mri_convert and see if that works

External Email - Use Caution

Hello Team,

I was working on mind boggle data set. I downloaded the freesurfer results from "https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/HMQ..."

I am unable to convert aseg.mgz to aseg.nii for HLN group. Please note that i was able to convert all other groups(MMRR, NKI-TRT, NKI-RS).

Command i tried "mri_convert aseg.mgz to aseg.nii" it throws cannot allocate memory error, where as it works for all other series other than HLN.

I have attached the screen shot of error message for your reference.

Can you please help me out?

Thanks, RItesh Mahajan
