Hence, you are saying I should run recon-all -autorecon1 -i -s subjid then replace the FS generated brainmask.mgz with my own stripped volume. Also, should I run recon-all -autorecon2 with wm segmentation ( after replacing the stripped volume ) and replace FS generated wm.seg.mgz with my wm segmentation volume? Thank you.

I would run autorecon1 witth skull stripping, then replace it with your own stripped volume (the brainmask.mgz). It will treat that as a "manual edit" since brainmask.mgz will be different than brainmask.auto.mgz, and hence it won't override it

Thank very much Bruce. Does it mean I have to run recon-all -autorecon1 -noskullstrip, then recon-all -autorecon2 -nosegmentation ( with the skull stripped volume) . Finally, recon-all -autorecon2-wm -autorecon3 -s subjid( with the wm and lesion stuff)? Thanks > Sent from my BlackBerry 10 smartphone.

Hi Paul
hmm, you have to be a bit careful with the -no* flags as you want to avoid running those steps, but you want make sure FS knows that the typical output of the steps you skipped exists and should be used. Others can help you with the logic of recon-all better than I can, but I think you are probably best off replacing the relevant volumes and running from there forward. You might need to run autorecon1, then insert your skull-stripped volume, then autorecon2, insert your wm and lesion stuff, then run autorecon2-wm, but I'm not totally sure since what you are doing is so non-standard.
cheers Bruce

We have already skull stripped and white matter segmented volume ( used lesion explorer) . Hence, I want to replace freesurfer 's generated outputs for this steps ( brainmask.mgz for skull strip and wm.seg.mgz (not wm.mgz ) for white matter) with ours. I know recon-all -all performs all 31 steps and inserting " -nostep " flag tells freesurfer to skip that step. Covering and Creating a symbolic link to our files and then, running the remaining steps of recon-all might help achieve this ( I believe) . Replacing this freesurfer outputs with ours will reduce time spent on pial and white matter edits. Best, Paul

Hi Paul
can we take a step back. What are you trying to achieve by avoiding these steps?
cheers Bruce

Thanks Bruce. Another question, since " -no segmentation " flag skips the white matter segmentation step of recon-all. Can I also use the same logic as the "-noskullstrip" flag to replace the wm.seg.mgz file? That's, run " recon-all -autorecon1 -autorecon2 -nosegmentation -s subjid ". Then copy/convert my already segmented brain and name it wm.seg.mgz. After that, treat it as if I had freesurfer's wm.seg.mgz and finally, run " recon-all -autorecon3 -s " to complete the process. What do you think? Best, Paul

Hi Paul
we required the T1.mgz, brainmask.auto.mgz and brainmask.mgz volumes so must create them somehow. I think if you copy/convert your already-stripped and name it brainmask.mgz we should treat that as if you had edited our skull stripping and you should be able to run from their forward (autorecon2 and autorecon3 I believe)

Please can someone answer this. Thanks " Hello Freesurfer, I have couple of questions. While going through the frequently asked questions on your pagehttp://freesurfer.net/fswiki/UserContributions/FAQ%C2%A0I came across a question regarding how to integrate a skull stripped from another problem into freesurfer (using recon-all -autorecon1 -noskullstrip -s subjid ----> create a symbolic link from T1.mgz to brainmask.auto.mgz and another like from brainmask.auto.mgz to brainmask.mgz ------> after run the finall stages of recon-all: recon-all -autorecon2 -autorecon3 -s subjid).
First question, isn't T1.mgz, brainmask.auto.mgz and brainmask.mgz created during skull stripping? why are they present if I included the "-no skullstrip" flag?
Second question, where do I insert my already skull stripped data in the symbolic link?
Last question, the final stages of recon-all ( recon-all -autorecon2 -autorecon3) doesn't include skull stripping, how can I be sure my skull stripped data was incorporated into the freesurfer recon-all process?
Best, Paul
