rostral anterior cingulate fix?
by Zeng,Victor (BIDMC - Psychiatry) 05 Jul '19

05 Jul '19

Hi Freesurfer group - I'm using FS6.0 dev-20190118, and I'm processing a few brain scans. I'm seeing a misparcellation of the right rostral anterior cingulate using tkmedit (I know tkmedit is sorta deprecated), and it doesn't seem inappropriate to use control point fixes. How would you best fix this (I'm open to using freeview), without just editing the aparc+aseg.mgz?

Re: [Freesurfer] Error in mris_convert thickness file from ascii format

External Email - Use Caution Hi Bruce, I obtained the curv vector and used read_surf.m to get the face lists in lh.inflated for fsaverage. If the faces list was generated as a 327680x3 double, would it be correct to say that the number of faces is 327680 as the input argument for write_curv.m? Thanks so much for your help, JeeSu -- Date: Thu, 4 Jul 2019 12:56:57 -0400 (EDT) From: Bruce Fischl <fischl(a)nmr.mgh.harvard.edu> Subject: Re: [Freesurfer] Error in mris_convert thickness file from ascii format To: Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu> Message-ID: <alpine.LRH.2.20.1907041253020.916(a)door.nmr.mgh.harvard.edu> Content-Type: text/plain; charset="utf-8" Hi JeeSu which surface you use is irrelevant (we only need one with the right topology). As for converting from ascii back to curv, matlab is probably the easist using read_ascii_curv.m and write_curv.m. You will need to also read in a surface to get the number of faces. Again, any one of the same topology ones should be fine (e.g. lh.inflated for lh.thickness.asc) cheers Bruce

Change image orientation

External Email - Use Caution Dear Freesurfer devs, Is possible to change the image orientation of the t1.nii images? In that case, what command should be used?. I would like to change them from a LPI orientation to a RAI orientation. Best regards, -- *Miguel Ángel Rivas Fernández*

External Email - Use Caution Hi Bruce and Doug, Thanks for your responses. Apologies if my query was unclear. The operation I would like to do is the opposite: instead of converting *to* ascii, I want to convert *from ascii to curv format.* I used the command stated in your replies to do the first conversion to ascii, which I required in order to carry out an algorithm for correcting for site effects on the dataframe of vertex-wise thickness values. Now that I have done that, I was hoping to convert back into the original curv format in order to carry out the normal group comparison pipeline (mri_preproc, mri_glmfit). Is this possible, from your view? A slightly tangential note: when I did the first conversion to the ascii format, I used lh.inflated as the surface-- would this have had a significant impact on what I am attempting to do now?

Doubts in hippocampal subfields labeling
by Antonin Skoch 03 Jul '19

03 Jul '19

External Email - Use Caution Dear experts, I noticed that systematically in most of my subjects there is area in hippocampal region, labeled in aseg as hippocampus, but NOT labeled as hippocampus in hippocampal subfields segmentation (it has zero value there). See screenshots with norm.mgz overlaid by 1) aseg, 2) hippocampal subfields segmentation. According to T1 and T2 signal, it should neither be white matter and also probably not a ventricle/CSF. Neocortex is not located here. It has similar signal intensity as hippocampus, so I think that it should be hippocampus, but I am puzzled by hippocampal subfields segmentation results there. Why it is not labeled? Could you please help me to clarify this? My concern is to correctly label this area. I could upload the example subject if it is of any help. Regards, Antonin Skoch

Error in mris_convert thickness file from ascii format
by Jee Su Suh 03 Jul '19

03 Jul '19

External Email - Use Caution Hello, I am trying to convert ascii files containing vertex-wise thickness data into binary curvature files for subsequent smoothing and input into mri_glmfit. The command I used is: mris_convert lh.test.asc lh.test.thickness But then get the following error: ERROR: MRISalloc: nfaces=-5 < 0 No such file or directory I'm not sure what file or directory the error message is referring to, nor what the meaning of nfaces is. I am running version 6.0 on macOS Mojave. I have also attached a truncated version of the ascii file for inspection purposes (the whole thing was too big), which was converted from a csv that was generated by a python script correcting for site effects. This script took in as input the original ascii converted from the original lh.thickness file using mris_convert. The coordinates correspond to the fsaverage template (~160k vertices in the whole file). Thanks in advance for any guidance, -- JeeSu Suh, BSc. PhD.
