It's a little involved but possible. 1. Binarize Nth cluster to have a binary value of N mri_binarize --i N.nii --min 0.5 --binval N --o Nb.nii 2. Sample Nth cluster to the surface mri_vol2surf --reg register.dat --mov Nb.nii --interp nearest --hemi lh lh.Nb.mgh After doing that will all clusters, combine them together with mri_concat lh.1b.mgh lh.2b.mgh ... --vote --o lh.seg.mgh Now create a surface annotation mris_seg2annot --seg lh.seg.mgh --hemi lh --s subject --o lh.seg.annot --ctab yourctab yourctab is a color table like $FREESURFER_HOME/FreeSurferColorLUT.txt. You list your regions and give them the colors you want. doug vin . wrote: > Hi Doug, > sorry for confusing names. > > - 1.nii is name of the cluster, which I want to overlay. it's a > coritical region, resulted from fsl-probtrackx. > I want to have few color codes in RGB > R G B > 1. 255 0 255 > 2. 116 0 116 > 3. 0 0 255 > ... > > in this way, I would like to overlay 20 cortical regions in different > colours on inflated brain. > > -fthresh 0.3 > here > (1/(10^0.3) == 50.12 % > in freesurfer email archieve, I found this. hope it's correct. > > Thank you > > > > > On Mon, Dec 12, 2011 at 11:11 PM, Douglas N Greve > <greve(a)nmr.mgh.harvard.edu <mailto:greve@nmr.mgh.harvard.edu>> wrote: > > Hi Vin, why do you say it's a 50% threshold?

Hi Doug, following up on my problem with preprocessing, here is the line that we ran: preproc-sess -sf sessid3 -df sessdir -per-run -sliceorder siemens -fsd bold -fwhm 0 -mni305-2mm -surface self lhrh -force the part that is failing is: mc-afni2 --i 004/f.nii.gz --t 004/template.nii.gz --o 004/fmcpr.nii.gz --mcdat 004/fmcpr.mcdat that line calls 3dvolreg.afni, which is the part that is really failing: 3dvolreg.afni -verbose -dfile 004/fmcpr.mcdat -1Dmatrix_save 004/fmcpr.mat -base 004/tmp.mc-afni2.24802/tempvol.nii.gz -prefix 004/tmp.mc-afni2.24802/outvol.nii.gz 004/tmp.mc-afni2.24802/invol.nii.gz we tried running it without the .afni extenstion, so using the actual afni 3dvolreg and got no error message: 3dvolreg -verbose -dfile 004/fmcpr.mcdat -1Dmatrix_save 004/fmcpr.mat -base 004/tmp.mc-afni2.24802/tempvol.nii.gz -prefix 004/tmp.mc-afni2.24802/outvol.nii.gz 004/tmp.mc-afni2.24802/invol.nii.gz This is the output for mc-afni2: mc-afni2 --i 004/f.nii.gz --t 004/template.nii.gz --o 004/fmcpr.nii.gz --mcdat 004/fmcpr.mcdat /ncf/vcn/Maryam/mri-space/studies/SM_PDM/unpackdata/111206_xu_SM_PDM_05/bold mri_info --nframes --o /tmp/mriinfo.24802 004/template.nii.gz log file is 004/fmcpr.nii.gz.mclog mcdat file is 004/fmcpr.mcdat tmp dir is 004/tmp.mc-afni2.24802 #@# -------------------------------- /ncf/vcn/Maryam/mri-space/studies/SM_PDM/unpackdata/111206_xu_SM_PDM_05/bold mri_convert 004/template.nii.gz 004/tmp.mc-afni2.24802/tempvol.nii.gz --nskip 0 --ndrop 0 -odt float mri_convert 004/template.nii.gz 004/tmp.mc-afni2.24802/tempvol.nii.gz --nskip 0 --ndrop 0 -odt float nskip = 0 ndrop = 0 $Id: mri_convert.c,v 1.179.2.2 2011/05/16 20:53:47 greve Exp $ reading from 004/template.nii.gz...

rtview: ERROR cannot find eccen/real.nii
by Michelle Umali 13 Dec '11

13 Dec '11

Dear All, I am still having trouble generating polar and eccen maps with rtview. I did this: cd $SUBJECTS_DIR/retinotopy/sj07/bold/rtopy.self.lh rtview.sh --s sj07 --lh --eccen \ --real eccen/real.nii --imag eccen/imag.nii --fsig eccen/fsig.nii The subjectname file is in $SUBJECTS_DIR/retinotopy/sj07 and I've tried when a copy of rtview is in $SUBJECTS_DIR/retinotopy/sj07/bold/rtopy.self.lh or in $SUBJECTS_DIR/retinotopy The error I got : ERROR: cannot find eccen/real.nii even though all the appropriate images exist in the directories and can be seen through tksurfer-sess. Where am I going wrong? Thanks. Michelle

Re: [Freesurfer] convert surface label on to functional image

The easiest thing is to use mri_label2vol, something like mri_label2vol --label yourlabel.label --temp functemplate.nii --reg register.dat --proj frac 0 1 .1 --hemi lh --subject subject --o yourlabel.nii doug Zhangyuanchao wrote: > Thanks for your response! > > In fact, the label that I want to convert to functional space was > obtained by between-group comparisons, so it does not belong to any > existing parcellation template. > > What should I do in this case? > > Thanks! > > Best, > > --- *11年12月13日，周二, Douglas N Greve > /<greve(a)nmr.mgh.harvard.edu>/* 写道： > > > 发件人: Douglas N Greve <greve(a)nmr.mgh.harvard.edu> > 主题: Re: [Freesurfer] convert surface label on to functional image > 收件人: "Zhangyuanchao" <woshizhangyc(a)yahoo.cn> > 抄送: freesurfer(a)nmr.mgh.harvard.edu > 日期: 2011年12月13日,周二,上午5:48 > > Hi Yuanchao, I would recommend that you use the aparc+aseg.mgz > file for this.

Cluster-wise correction for multiple comparisons: customized Zstats data
by Xinian Zuo 13 Dec '11

13 Dec '11

Hi List, I have a question on how to write out the matlab vector containing the Z-statistics and perform subsequent multiple corrections. I already read some functions and know how to write it to a mgh surface file. Here, my question is 'is there any specific things on the header of the surface file, which allows me to do cluster-wise correction (see corrected p-value < 0.025) if there is such a command for that?'. Thanks! -- Xi-Nian Zuo, Ph.D of Applied Mathematics (http://lfcd.psych.ac.cn) Google Scholar Citations: http://scholar.google.com/citations?user=a3-gVGMAAAAJ&hl=en

problem using an older environment...
by Joe Andreano 12 Dec '11

12 Dec '11

Hello folks, I'm trying to reanalyze some old data that was originially analyzed in freesurfer version 4. Because the code I was using was from 4.0, I set the environment to 4 before starting, then made a new analysis and a few new contrasts. When I tried to run selxavg3-sess with the following command: selxavg3-sess -analysis nmdm_ALL42_V_fix -sf SESSID_ALL_FINAL -df . I got the following error message: /autofs/space/albus_003/users/nmdm_2/nmdm_004 ---------------------------------------- $id:fastselxavg3.m, v 1.88.2.5 2010/11/11 16:55:08 greve Exp $ /usr/local/freesurfer/stable5_0_0/fsfast/toolbox/fast_selxavg3.m /usr/local/freesurfer/stable5_0_0/fsfast/toolbox/fast_ldanaflac.m /usr/local/freesurfer/stable5_0_0/matlab/MRIread.m --------------------------------------- outtop = /autofs/space/albus/3/users/nmdm_2 Extension format = nii.gz ???

Note also that the code being used here is adapted directly from an earlier analysis which was run in version 4 and which I know worked without errors. Anybody have any idea what's happening here? Even some information on what 'mcstem', or ldanaflac do would be helpful. (I have attached my analysis.info file) Thanks, Joe Andreano _________________________________ Joseph M.

12 Dec '11

Dear FreeSurfer list, Greetings! a newbie to freesurfer. -- would like to overlay tracking group results (Sum from all subjects)-(from FSL ) in the inflated lh & rh. -- - it works with one region (hope it's correct), with following command, where, -fthresh ?? means it shows 50 % threshold based on intensity / only voxels which are overlaid by atleast half of the subjects ?? >tksurfer #Sub_ID lh inflated -annot aparc.annot -ov 1.nii -ovreg register.dat -fthresh 0.3 -fmid 0.3 -fslope 1 - How I can overlay multiple regions, in specific colours, with 50% thr. ? , Thank you :) Vin

convert surface label on to functional image
by Zhangyuanchao 12 Dec '11

12 Dec '11

hi, expert, By mapping a surface label to a functional template, I want to extract the corresponding cortical gray matter region in the functional space. I know I should use the mri_label2vol command. In the help page of mri_label2vol, I see some examples of this command. 2. Convert a surface label into a binary mask in the functional space.Fill in all the cortical gray matter. Require that a functional voxelbe filled at least 30% by the label: mri_label2vol --label lh-avg_central_sulcus.label --temp f.nii --reg register.dat --fillthresh .3 --proj frac 0 1 .1 --subject bert --hemi lh --o cent-lh.nii 3. Convert a surface label into a binary mask in the functional space.Sample a 1mm ribbon 2mm below the gray/white surface. Do not require a fill threshold: mri_label2vol --label lh-avg_central_sulcus.label --temp f.nii --reg register.dat --proj abs -3 -2 .1 --subject bert --hemi lh --o cent-lh.nii I want to extract the cortical gray matter on the functional images corresponding to the surface label. I do not know which of the above commands could obtain the result I want and which parameters I should use to obtain what I want. For example 3, I do not quite catch what "Sample a 1mm ribbon 2mm below the gray/white surface. " this sentence means. Thanks for your help! Best Yuanchao

Converting thickness maps to vtk
by Navid Shiee 12 Dec '11

12 Dec '11

Hello, I was wondering if there is a command like mris_convert to create a thickness map in vtk format (either on the white or pial surface) ? Thanks, -- Navid Shiee Ph.D. Candidate Laboratory of MEDical Image Computing (MEDIC) Image Analysis and Communication Laboratory (IACL) Johns Hopkins University
