hi Lysianne and Paul,

hope you don't mind me jumping in here; i'm having a very similar issue with some 7T MP2RAGE data (which i denoised first); see attached after an SSwarper run.

did you find a solution to Lysianne's problem? i've run 3 other subjects from this dataset through SSwarper and they finished fine. note that the final anatQQ*.nii image looks okay *at first glance*, but it seems to have taken this bad native-space skull-strip and performed an extreme warp on the remaining parietal to match the MNI template shape.

so as for this subject, i could start troubleshooting with the 'lpa' cost suggestion, or something like -SSopt -push-to-edge, etc but if you've already arrived at a solution i'd love to try that first because as we know SSwarper takes a while. let me know if you'd like more info or data or scripts (i just ran the most vanilla SSwarper command possible). thanks!

-Sam
