Hi Lilla, thanks for the advice, I'll just upgrade my RAM to 24 GB (maybe it will help FSFAST too ;-)). I used the --m3d flag as a blind guess about the possible cause of the aforementioned error, thank you for clearing that up, I'll skip it next time.

Best regards, Marcel

Hi Marcel, You would ned at least twice as much. Also, is there a specific reason for you to use the --m3d flag? That will result in writing out uncompressed morph files which will take up a lot of space. Lilla

Dear FreeSurfers,

I'm trying to use mri_cvs_register, however the process can't complete and I get the following error: [...] loading transform id string = data size = 18728074 uilen = 6 loading transform id string = data size = 19845421 uilen = 6 loading transform id string = data size = 19120776 uilen = 6 loading transform id string = data size = 71 uilen = 7 loading transform id string = saveTransform code writing transform size = 117019458 saveTransform code writing transform size = 117019458 saveTransform code writing transform size = 16 saveTransform code writing transform size = 21339696 saveTransform code writing transform size = 21092930 saveTransform code writing transform size = 20795616 saveTransform code writing transform size = 20591898 saveTransform code requested buffer size = 436643894 Exception caught while saving morph ZlibStringCompressor::**setBufferSize - Caught std::bad_alloc

My command line was: mri_cvs_register --mov subject01 --mni --openmp 8 --m3d

At the time of crash all RAM is consumed by createMorph process (10 GB). Is this crash related to the ammount of RAM on my machine (12 GB)? If so, how much RAM is needed to complete mri_cvs_register?

Best regards, Marcel
