Re: [Freesurfer] Freesurfer dev version : recon all error mpr2mni305

Hi Richard, thanks for pointing this out – I’ll take a look into it. best Andrew From: <freesurfer-bounces(a)nmr.mgh.harvard.edu> on behalf of "Jones, Richard" <richard.jones(a)choa.org> Reply-To: FS Help <freesurfer(a)nmr.mgh.harvard.edu> Date: Thursday, April 19, 2018 at 9:49 AM To: FS Help <freesurfer(a)nmr.mgh.harvard.edu> Subject: [Freesurfer] Freesurfer dev version : recon all error mpr2mni305 I ran the command shown below to do recon-all on DICOM images from a Philips Ingenia scanner using the development version of freesurfer on a Mac running high Sierra. recon-all -i /Users/Shared/HOPE_SS_Data/HOPE_SS020_Anat/IM-0001-0001.dcm -subject HOPE_SS020 –all The program crashed with the error “ERROR: mpr2mni305 failed, see transforms/talairach_avi.log” The talairach_avi.log file is shown below, followed by the log file. As a test I ran the same command, on the same data, using Freesurfer 6 and that ran without problems (except that it didn’t handle the diffusion tags in the Philips DICOM header correctly so I had to set FS_LOAD_DWI=0, this was not a problem in the development version). Any suggestions as to what may be causing the problems with the library in the development version?

hippocampal segmentation development version question
by Maureen McHugo 19 Apr '18

Hi, I am interested in using the head/body/tail output from the hippocampal subfield segmentation module. Is there a reference or description of what landmarks were used to separate head/body and body/tail? Thanks! Maureen

Lateral Geniculate Nucleus (LGN) roi or volume measures?
by Yash Patel 18 Apr '18

18 Apr '18

Hi all, Is there any way to obtain (automatically, n~1000 subjects), LGN volumes from the Freesurfer set of tools? Or somehow transform the ROI from an atlas into subject space, then extract volume data? Thanks, Yash

problem with mri_label2vol for aseg
by Michelle VanTieghem 17 Apr '18

17 Apr '18

Hi Freesurfer experts, I am trying to convert the aseg back into native space of the anatomical T1 image. I followed the instructions as in the webpage: https://surfer.nmr.mgh.harvard.edu/fswiki/FsAnat-to-NativeAnat specifically this line of code: cd $SUBJECTS_DIR/<subjid>/mri mri_label2vol --seg aseg.mgz --temp rawavg.mgz --o aseg-in-rawavg.mgz --regheader aseg.mgz However, the result is very odd. The aseg boundaries appear correct in the subcortical regions. however, at the gray mater boundaries, there are single voxels incorrectly labeled as different subcortical-regions. As a result, in the viewer, the gray matter boundaries look multicolored. This is problematic, as I would like to extract a mask of specific ROIs (e.g. right amygdala) but there are many other voxels labeled '54' in addition to the right amygdala. See attached images. I would greatly appreciate your assistance!! Thank you, Michelle -- Michelle VanTieghem PhD student in Psychology Developmental Affective Neuroscience Lab Columbia University mrv2115(a)columbia.edu

Map the vertices that show a relationship between the FC (obtained by FS-FAST)
by Piero Chiacchiaretta 17 Apr '18

17 Apr '18

Hi there, I wonder if the fsgd file and the command lines listed below are corrected. My sample included 4 groups with different diagnosis (g1, g2, g3, g4). I'm interested to map the vertices that show a relationship between the FC (obtained by FS-FAST) and cortical thickeness, regressing out the diagnosis. To this aim I used the --pvr option: mri_glmfit --y ces.nii.gz --wls cesvar.nii.gz --surface fsaverage rh --glmdir Thickness.wls --nii.gz --fsgd g4v1_thickness.fsgd --C intercept.mtx --C slope.mtx --pvr $SUBJECTS_DIR/rh.thickness.10B.mgh The fsgd file lists: ------------------------------------------------------------- GroupDescriptorFile 1 Title Relationship FC-thick reg out dignosis Class g1 Class g2 Class g3 Class g4 Input XX1 g1 Input XX2 g1 ...

FSFAST, Beta values and Percent Signal Change questions
by Sarah Cole 17 Apr '18

17 Apr '18

Hi Doug, I need your recommendations on two topics. I really appreciate your help. 1.) I have two runs of the same experiment, each for about 12 minutes. These 2 runs are different only in the presentation order of the stimuli. I also have one localizer session which first, I calculated my contrasts in it, found the active voxels with positive values, and made a mask of those voxels. Then, mapped the masks on those 2 runs and got the raw data within those voxels. So far, so good. Now, I am looking at the Beta values in these 2 runs for those active voxels, they are very different from each other. For example, in the first run, they are mostly positive but in the second run, they are mostly negative. My intuition was that they should be in the same ballpark. I cannot make sense of this. Do you have any suggestions on why this is happening? 2.) To calculate the % signal change, is it ok to pick the baseline whatever is suitable to my research question. For example, if I need to know the % signal change relative to* the average signal in the first TR of a specific block*, can I use that as a baseline? Or does it always need to be the rest or the mean? Thank you so much and looking forward to hearing from you. Sarah

how to use annotation file in FSFAST for seed based analysis
by Sims, Sara A 17 Apr '18

17 Apr '18

Hello, I am trying to use Glasser’s parcellation to create a correlation matrix that compares all parcels to all parcels. I am new to FSFAST, but so far I have gotten the data preprocessed and ready to go. But I am unsure how to proceed. I have rh and lh annotation files of the parcellation in fsaverage space and I am not sure what to do to them to get to the point that I can use “fcseed-sess”? Should I convert them to labels and then put them on each subject? But what do I do after that? Help please, Sara Sims

mri_deface keeps seg faulting
by Warner, Graham Cary 17 Apr '18

17 Apr '18

Hi, I'm trying to deface an MEMPRAGE dataset using the following command: [jazz:test_deface] (nmr-stable53-env) mri_deface outSubDir/mri/orig/001.mgz talairach_mixed_with_skull.gca face.gca sample_T1_input_defaced.mgz and am getting the output: logging results to sample_T1_input_defaced.log reading 'talairach_mixed_with_skull.gca'... reading 'outSubDir/mri/orig/001.mgz'... changing type of input volume to 8 bits/voxel... MRIchangeType: Building histogram Segmentation fault (core dumped) I'm using the Martinos center's default version of mri_deface located at /usr/local/freesurfer/stable5_3_0/bin/mri_deface. I'm using the talairach_mixed_with_skull.gca and face.gca sample files found on https://surfer.nmr.mgh.harvard.edu/fswiki/mri_deface but the actual input mgz came from a scanner here at the center. Maybe this is a CentOS 7 compatibility problem? Please let me know if there is any other information I can provide. Thank you, Graham
