Hi Elijah - This error occurs with one number of control points but not another? That would be very strange. I'd have to look at the full trac-al.log to figure it out, I can't guess what's going on just from this one line unfortunately. a.y On Fri, 19 Aug 2016, Elijah Mak wrote: Hi Anasta

Hi Anastasia, Thanks, it works, but only for MNI reg option. For the CVS stream, there was an error message during -prior. ERROR: fio_pushd: /Users/MacPro/Documents/22995_EM/dmri/xfms/cvs/final_CVSmorph_tocvs_avg35/mri This error message did not halt the process though. Could this be a clue? Th

Mmm, it sounds like the shape of the tract is too convoluted for it to find a good fit. I'd try increasing the # of control points. On Fri, 19 Aug 2016, Elijah Mak wrote: Hi Anastasia, Thank you for looking into that subject. I have tried reinitiliasation a few times and in all cases, it ju

Hi Anastasia, Thank you for looking into that subject. I have tried reinitiliasation a few times and in all cases, it just could not find a satisfactory control point fit during the -prior stage. Therefore, the -prior stage has been running for more than 10 hours now. This occurs in other a small

Hi Elijah - It looks to me like the forceps major had the same problem for both MNI and CVS in this subject, right? This subject has a relatively thin and somewhat convoluted forceps major, so you can try increasing the number of control points, say from 7 to 8. (But I'd try reinitialization

Dear Anastasia, I have also uploaded the file with the problem (22995_EM.zip), and this is how my config file looks like after modifications: set subjlist = (22995) set pathlist = (fmajor_PP) set ncpts = (7) set reinit = (1) Thanks again! Best Wishes, Elijah -- Elijah Mak PhD Candidate *|*

Hi Elijah - You add "set reinit =1" to the config file, (and remember to set the pathlist and subjlist to only what you want to rerun), and then rerun the -prior and -path steps in that order. Best, a.y On Thu, 18 Aug 2016, Elijah Mak wrote: Thanks for the tips on reinitialisation of tract

Hi Elijah - It looks like the CVS case needs to be reinitialized. In principle you're right that if the registration is good this shouldn't be a problem. It's hard to tell what might've caused this in an individual case without looking at the data. If you want me to look into it you can uploa
