Hi Catherine
I don't believe dicom supports compression. How are they compressed? Is it just gzip or some file compression? We need more information...

Hi Bruce,
We want to analyze some scans that were compressed when they were stored. Compression factor varies from 3:1 to about 7:1 or so. unfortunately, we don't have access to the "raw" dicom data. Can we do this? thanks for your help, cheers, catherine

Hi Experts,
We wanted to run clinical scans that underwent some compression at the scanner through freesurfer. I just wanted to seek confirmation that SPGR sequences that have undergone slight compression can not be run through freesurfer, is that correct?
thank you, catherine
