Hi Salvatore that is a very large defect - about 1/4 the size of a typical surface. Usually that means something big is wrong and you'll need to correct it manually. You can visualize the defects on the ?h.orig.nofix and ?h.inflated.nofix surfaces and use them to figure out what is causing the

Re: [Freesurfer] Data differ depending on OSX version

2016-01-05 Thread Martin Reuter
It is mainly the OS version, yet, sometimes the same OS can run on very different architectures (eg. on 32bit or 64 bit systems, or even tablets and phones), which could affect results. Starting with Lion, OSX only runs on 64 bit systems though. Best, Martin On 01/05/2016 02:09 AM, Kasper J

[Freesurfer] Is the x-component of the b vectors extracted by mri_convert inverted?

2016-01-05 Thread Emad Ahmadi
Hi FreeSurfer Experts, Happy New Year! I am using mri_convert to extract b vectors (bvecs) from diffusion images obtained at Bay 4. Then I use TRACULA for reconstructing white-matter pathways. The shape of the reconstructed pathways are odd, so I checked if the extracted bvecs are correct. T

Hi Ajay it's kind of dicey to use an arbitrary nightly build as we have no idea what was in that that might have been fixed the next day. I would wait for a beta, or at the very least try a new version as I don't think our current version exhibits the behavior you are experiencing. cheers Br

Hi Professor Yeo, Sorry for the late reply. In the end I ended up giving in and performing my functional connectivity analysis in MNI space, like any rational person would. As a result, I ended up using the MNI152 versions of network masks you provided. Thanks for all your help, and for pro

Dear experts, I'm trying to adopt the HCP pipeline to our own data but at it is originally developed for human adults it fails frequently on my data. A big chunk of the pipeline is based on FreeSurfer so I thought it should be most relevant to ask my question here. the main problem I have here is
