Dear SPM Experts and Users,
I posted the following content 2 weeks ago, since the issue has not been solved, hope you could read it again if you havenot got a chance before, thanks.
I am trying to get grey matter (and other matters) out of t1 MRI using SPM12. It worked on one group of the images, but not at all for another group of files. So far I cannot figure out why, just can see some difference between the two groups – the not working group has different original coordinates and maybe less contrast, and the working group may have gone through different preprocessing which I am not sure. For the NOT working group I tried to adjust almost all the parameters in SPM12, just got all 0’s as segment out.
Note: I tried another segment tool, it worked for the both group, but with too much redundant areas for both comparing to SPM. So I do want SPM work.
I will appreciate it very much if you could help solving the issue (e.g., tell exactly what parameters to choose, or how to pre-adjust the images, etc.), or offer any hints. For your possible trying on, I upload the two files (about 40Mb, File1 belongs to not working group, File2 belongs to working group) to owncloud, the link:
