External Email - Use Caution Please ignore my last email. I added --out_type mgh and also changed the --out to end with ?h.mgh and it's done the trick. Please do let me know if this isn’t correct though! Cheers, Mason Mason T Wells, MSc PhD student School of Optometry and Visio

External Email - Use Caution Sorry, just to follow up on this. The surface based analysis needs the outputs in the format of MGH. I fear I may have missed a step here. Any advice would be great. Cheers, Mason Mason T Wells, MSc PhD student School of Optometry and Vision Science

External Email - Use Caution Great, thanks for this. Am I right in thinking that the only outputs from this command are COR-.info and COR-001 and that neither of these should have which hemisphere it was created from in their name? I also notice the examples on the wiki page have

That looks good. The only thing to change is to specify the projection fraction for vol2surf to --projfrac 0.5 (so that it samples in the middle of the cortical ribbon rather than at the white/gray boundary) On 4/17/2020 1:36 PM, Mason Wells wrote: > External Email - Use Caution > > Hi,

External Email - Use Caution Hi, Can I just double check this seems correct to you experts? I am not 100% proficient in Freesurfer/FSL. I ran: bregister --s S1 --feat Data/Feat2/LM/scans/Preprocessed_functionals/6_CMRRMB_run1_.feat/ Which seemed to give me what I needed, the

Yes, use the template.nii.gz as the registration target. A long time ago we used to have some wrappers that would operate directly on feat folders. Not sure if they still work but, check out https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/FslFeatFreeSurfer On 4/17/2020 10:43 AM, Mason Well

oh, then you probably want to use bbreg to register it and mri_vol2surf to sample it onto the surface. Doug is the expert on this and can add/correct if this is not the whole story :) cheers Bruce On Fri, 17 Apr 2020, Mason Wells wrote: External Email - Use Caution Hi Bruce, The on

External Email - Use Caution Hi Bruce, The only pre-processing I have done is the motion correction, high pass filtering and distortion correction. So, as far as I know it is still in the volume and in the original functional space. Best wishes, Mason Mason T Wells, MSc PhD st
