make_average_subject memory issues
by Lars M. Rimol 07 Jun '06

07 Jun '06

Hi, I just ran make_average_subjects with increased swap (from 2G to 8G) on 178 subjects and now it worked, which would seem to indicate that it may have been a memory issue? I did not crash with 3, 10 and 113 subjects with 2G swap. yours, LMR >Hmmm, I've run it on >100 subjects without trouble. I'll try now and see if >I can replicate locally.

Re: [Freesurfer] errors in library in new version of Freesurfer

Thanks for the question. Here is the info that I can provide. (1) When I did 'source' the *.csh, there was no error. here is the output -------- freesurfer-Linux-centos4_x86_64-stable-pub-v3.0.3 -------- Setting up environment for FreeSurfer/FS-FAST (and FSL) FREESURFER_HOME /usr/local/freesurfer FSFAST_HOME /usr/local/freesurfer/fsfast SUBJECTS_DIR /usr/local/freesurfer/subjects FUNCTIONALS_DIR /usr/local/freesurfer/sessions MINC_BIN_DIR /usr/local/freesurfer/mni/bin MINC_LIB_DIR /usr/local/freesurfer/mni/lib PERL5LIB /usr/local/freesurfer/mni/lib/perl5/5.8.5 GSL_DIR /usr/local/freesurfer/lib/gsl QTDIR /usr/lib/qt3 TCLLIBPATH /usr/local/freesurfer/lib/tcltktixblt/lib FSL_DIR /usr/local/freesurfer/fsl (2) when I did, ldd 'which mri_convert', it gave me the following error message. ldd: ./which mri_convert: No such file or directory (3) When I did, however, just 'which mri_convert', it correctly points to its location, which is .........../freesurfer/bin/mri_convert. (4) Freesurfer is running on the latest version of SUSE on a 64-bit machine. I downloaded an appropriate version of Freesurfer. Nam. >>> Nick Schmansky <nicks(a)nmr.mgh.harvard.edu> 06/06/06 4:42 PM >>> What is the output when this is typed: source $FREESURFER_HOME/SetUpFreeSurfer.csh and this: ldd `which mri_convert` and what OS is this installed on?

errors in library in new version of Freesurfer
by Joongnam Yang 06 Jun '06

06 Jun '06

I installed the new version of Freesurfer by downloading from Freesurfer Wiki website. Then, I ran recon-all -subjid subjectname -autorecon1, and got the following library errors. Would someone suggest a solution? Nam. mri_convert: error while loading shared libraries: libgsl.so.0: cannot open shar ed object file: No such file or directory mri_convert: error while loading shared libraries: libgsl.so.0: cannot open shar ed object file: No such file or directory strings: 'mritotal:': No such file strings: 'Command': No such file strings: 'not': No such file strings: 'found.': No such file nu_correct: Command not found. .................

mri_volcluster example
by Paymon Hosseini 06 Jun '06

06 Jun '06

Hi Can you please post an example of "mri_volcluster" use with fsfast? more specifically, when i run : mri_volcluster \ --in /space/engram/12/users/pman/rk_fmri/Y15_111504/bold/rk_enc_sm5/RNeg_vs_Fix/sig \ --in_type bfloat \ --reg /space/engram/12/users/pman/rk_fmri/Y15_111504/bold/rk_enc_sm5/tal/register.dat \ --thmin 7 \ --minsize 640 \ --allowdiag i get the following error: NOT Adjusting threshold for 1-tailed test INFO: bvolumeRead: min = -16.6743, max = 25.5035 ERROR: Input volume voxel dimensions do not match those in the registration file. If the input volume is in bshort/bfloat format, check that there is an accompanying bhdr file. there are sig_xxx.bfloat and sig_xxx.hdr files in my "/space/engram/12/users/pman/rk_fmri/Y15_111504/bold/rk_enc_sm5/RNeg_vs_Fix/" directory. i am using "nmrenv" on engram.nmr.mgh any advice on how to resolve this? thanks a lot, paymon

Question regarding Outputs
by Goradia, Dhruman D 06 Jun '06

06 Jun '06

Hello all, The output of mris_anatomical_stats has a measurement called TotalWhiteMatterVolume for each hemisphere. From aseg.stat the measures for cerebellum-white volume and cerebral-white volume for each hemisphere can be obtain, but the sum of both the measures obtained from aseg is less than the total white matter volume obtained from the surface measures. Should they be different? If so what is the difference in measurement criteria? Thank you -Dhruman

freesurfer and monkey (macaque) brain processing
by Istvan Akos Morocz 06 Jun '06

06 Jun '06

dear freesurfer group, is there anywhere some cookbook-like instruction for processing monkey (macaque) brain MRI data with FreeSurfer ? are there any normalized macaque brain templates needed for FreeSurfer ? thanks, bye, pisti ----- pisti(a)bwh.harvard.edu

Problems runing a complete freesurfer analysis under Centos4 X86-64
by jorge luis 05 Jun '06

05 Jun '06

Hello all I have a Dual core Intel Pentium 3.0Gz machine with 2GB RAM and two SATA2 Hard Disks (300 GB and 80GB, respectively). I have successfully installed Linux Centos4 X86-64 (on the 80 GB disk) and the corresponding freesurfer version. I have run several freesurfer commands successfully (eg. tkmedit bert orig.mgz). The problem is when I try to run a complete analysis (recon-all - autorecon-all), the corresponding terminal gets stop undefinedly when it has to execute a copy operation (e.g. cp aseg.auto.mgz aseg.mgz). That is to say the problem get rise when freesurfer sends a copy order to the operating system. Manually I carry out the copy command and I don't have any problems. But when I reactivate freesurfer (eg. recon-all - autorecon2-cp) the terminal stops again when it has to carry out a copy operation again. I have another Intel Dual Xeon Dual Core 2.8Gz 5GB RAM machine with Linux Centos 4 X86-64 and the same configuration. No problem is there. Any tip to overcome this problem is welcome Thank you in advance Jorge ______________________________________________ LLama Gratis a cualquier PC del Mundo.

problems with make_average_subject
by Lars M. Rimol 05 Jun '06

05 Jun '06

Hi, I am analysing a dataset with 180 subjects. When I run make_average_subjects it crashes, the error message usually being something like this: mghRead: encountered error executing: 'zcat /space/monkeys/1/home/lmr/subjects/VETSA_test/testAVG/tmp/make_average_vol-tmp/orig- 19963b.mgz',frame -1 I have tried running it with fewer subjects and it worked with 3, 10 and 73 subjects. Also, it crashes at different points in the processing stream, so once it crashed at subject # 130, which I removed from the list of subjects, and then next time it crashed at # 30. My frist guess was that it is a memory problem. I tried running the top command in a different terminal at the same time as running make_average_subject with 2 and 10 subjects, and it seemed to require up to 400m of virtual memory and 10% of memory, but I couldn't see any difference in memory demands between running 2 and 10 subjects. This was running with 4G of physical memory and 2G of swap. Is this a known issue? (Couldn't find anything in the mailing list archive..) Thank you! -- yours, LMR

make_average_subject
by Lars M. Rimol 05 Jun '06

05 Jun '06

Hi, I have two questions on make_average_subject 1) Why are two sets of surfaces created by the make_average_subject script? What is the difference between e.g. inflated and inflated_avg? Which one(s) should be used for visualization? 2) As far as I understand, make_average_subject is run for visualization purposes only, and the output is not critical for the integrity of the statistical analyses (recon-all does the spherical warping and registration, and t he mris_preproc script makes sure the tesselation is uniform across the data set). So, does it matter if there are defects in the surfaces created by make_average_subject? I tend to get topological defects in the inflated_avg. Thank you! -- yours, LMR
