Average myelination within ROI
by SHAHIN NASR 06 Jul '17

06 Jul '17

Hi Surfers, I want to measure the average amount of myelinations within my ROI(s), I have already generated my myelination maps on surfaces (e.g. lh.myelin_ProjFrac0p5.nii ). Then I used mri_segstats as below: mri_segstats --i lh.myelin_ProjFrac0p5.nii --slabel SBJ_001 lh lh.V1 --sum V1_Stats.txt --accumulate but the numbers don't make any sense. For instance: # ColHeaders Index SegId NVertices Area_mm2 StructName Mean StdDev Min Max Range 1 0 125261 82573.4 Seg0000 110280.4453 0.2922 -5.5000 51.0000 56.5000 2 1 1138 764.8 Seg0001 941.0988 0.1572 0.2675 1.4203 1.1527 How can mean=941.0988 when the max=1.4203 ???

mri_cvs_register failure from missing shared lib

FSFAST mkcontrast-sess with spmhrf 2 question
by Joseph Dien 25 Mar '16

25 Mar '16

Hi, I have a question about how mkcontrast-sess works. I ran an analysis using the mkanalysis-sess option spmhrf 2 so there are three regressors for each predictor, the primary, the latency, and the dispersion. When specifying the contrast weights for mkcontrast-sess, the documentation indicates that they are specified in terms of the conditions as numbered in the paradigm file, not the individual regressors. Furthermore there only appears to be one contrast value output for each contrast, not three. How are the three regressors being handled? I can think of several scenarios: 1) the contrast weights are not actually in terms of conditions (the documentation is incorrect), they are actually in terms of the regressors (so contrasting conditions 1 and 2 could be specified as -a 1 -a 2 -a 3 -c 4 -c 5 -c 6). 2) the latency and dispersion regressors are being ignored (a common practice). The contrast weights should therefore be specified as -a 1 -c 2. 3) The Calhoun et al (2004) approach is being used to combine the three regressors into a "derivative boost" amplitude measure. The contrast weights should therefore be specified as -a 1 -c 2. Thanks for any help you can give me!

some questions about optseq
by charujing123 15 Jan '16

15 Jan '16

Hi FS experts, I try to design the schedule by optseq2. However it is beyond my ability as our experiment has a little complicated. Here is our goal: two successive trials decide condition. For example, this is our sequence:2 2 1 1 2 2 2 1 1 2 2 1 2 1 1 2 1 2 2 1 1 1 1 2 2 2 2 1 1 1 2 1 2 1 1 1 1 1 1 2 1 2 1 2 1 2 1 2 2 1 1 2 2 2 2 2 2 1 1 1 2 2 2 1 2 2 2 2 1 2 2 1 1 2 1 1 2 1 1 1 2 .22 and 11 is the same condition(this condition has 40 repeats); 12 and 21 is the same condition(this condition also has 40 repeats). That is to say, there are two conditons in this run. 81 trials in this run, and each trial has 1.5s intervels. And mean intertrial intervals is 3.5s. Our TR is 2s. According the efficiency about these two conditions, how could I design the intertrial intervals to get a appropriate sequence? I tried this: optseq2 --ntp 203 --tr 2 --psdwin 0 20 --ev ev1 2 40 --ev ev2 2 40 --nkeep 2 --o ex2 --nsearch 1000 Although it echo a result, I know, it is not what I need, because of every condition having two trials. So how I complete that? Thanks. All the best. Rujing Zha 2014-06-20 charujing123

DEPRECATED warning in Freesurfers
by Peter Wendorff 13 Oct '15

13 Oct '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi. I'm working with freesurfer as a software developer in a cloud project. My task is to enable control of freesurfer via network (e.g. REST interfaces). That works fine so far, but I stumbled over the following pearl deprecated warning: "Use of ?PATTERN? without explicit operator is deprecated at /usr/local/freesurfer//mni/bin/sharpen_volume line 153." Which has been printed to the log files repeatingly. I'm not a pearl expert, but I think, it's due to a more up to date pearl version used here, that deprecated the usage of ? delimiters for patterns without explicit operator. Using / as a delimiter works fine. I changed that locally to (new line 153): ($output_volume =~ /^([\S]+).mnc/) && ($base_name = $1) || die "sharpen_volume failed: output volume does not appear to be" ." a minc volume.\n"; (the original code here was): ($output_volume =~ ?^([\S]+).mnc?) && ($base_name = $1) || die "sharpen_volume failed: output volume does not appear to be" ." a minc volume.\n"; I'm not sure this is the best solution. It's even not strictly necessary to change this - it's only a warning that's thrown; but I think, it's useful. How can I submit this as a patch? Is it enough to report here? What to do? regards Peter Wendorff P.S.: For referene the header parameters of my sharpen_volume for revision comparison: #---------------------------------------------------------------------------- #$RCSfile: sharpen_volume.in,v $ #$Revision: 1.1 $ #$Author: bert $ #$Date: 2003/04/16 14:29:34 $ #$State: Exp $ #--------------------------------------------------------------------------- # ------------------------------ MNI Header - ---------------------------------- #@NAME : sharpen_volume #@INPUT : #@OUTPUT : #@RETURNS : #@DESCRIPTION: modifies intensities so as to produce a sharper histogram #@METHOD : #@GLOBALS : #@CALLS : #@CREATED : February 28, 1996 #@MODIFIED : #----------------------------------------------------------------------------- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlGTa5kACgkQi8ffXNvWmYSCUQCghMg1EffqfeJK4PSfo20uF8/J H0MAnjJc0WbHPf5gLDUw70K8fnQPjS+L =g+6e -----END PGP SIGNATURE-----

Creat ROI from annotation file
by wangzhiwei3233 01 Dec '14

01 Dec '14

Hi Freesurfer experts, I want creat some ROI masks or parcellation from Caret PALS_B12_Visuotopic.annot file in fsaverage's label folder. I used the command mri_label2vol, mri_label2vol --annot $Dir/label/lh.PALS_B12_Visuotopic.annot --temp $Dir/mri/T1.nii --fillthresh .5 --o PALS_B12_Visuotopic.nii --subject fsaverage --hemi lh --identity The parcellation in output volume were like some lines located at the boundry of white matter , and did not cover the gray matter (see picture). Then, I used another methods as follows. Firstly, I converted the annotation file into some label files using mri_annotation2label command; Secondly, I created ROIs using these labels by mri_vol2roi. However, the masks also couldn't cover the gray matter. Could anyone help me creat good masks? Thanks a lot! Zhiwei

broken X extension library
by Bart Boets 30 Nov '14

Hello, I have been running recon-all and trac-all analyses through remote access on the openmind.mit.edu cluster (from a windows7 i7 laptop using MobaXterm). The following software was set available: module add openmind/fsl/5.0.7 module add openmind/freesurfer/5.3.0 module add openmind/git module add netcdf/gcc/64/4.3.1.1 module add cuda55/toolkit/5.5.22 export LD_LIBRARY_PATH=/om/user/satra/projects/SAD/scripts/lib/:$LD_LIBRARY_PATH export LD_LIBRARY_PATH=/om/user/ksitek/HCP/scripts/lib/:/cm/shared/apps/cuda55/toolkit/5.5.22/lib64:/cm/shared/apps/cuda55/toolkit/5.5.22/lib:/cm/shared/apps/cuda65/toolkit/6.5.14/lib64:$LD_LIBRARY_PATH I guess all analyses went fine, but when I try to inspect output data by using freeview I encounter the following problem: I can open Freeview but when it tries to open a brain volume, the software always crashes and gives this error message: boets_env[20:08][2.53][26%]bboets@openmind:dmri$ freeview -v dtifit_FA.nii.gz & [1] 7594 boets_env[20:09][2.58][26%]bboets@openmind:dmri$ X Error: BadRequest (invalid request code or no such operation) 1 Extension: 146 (Uknown extension) Minor opcode: 187 (Unknown request) Resource id: 0x8000c3 [xcb] Too much data requested from _XRead [xcb] This is most likely caused by a broken X extension library [xcb] Aborting, sorry about that. freeview.bin: xcb_io.c:735: _XRead: Assertion `!xcb_xlib_too_much_data_requested' failed.

(likewise if I try to visualize images through mricron on the server it works extremely slowly and unreliably ...) Do you have any advice on how to handle this? I did not find any solutions in the archive? Thanks!
