[error] no installation candidates for curl
by Darko Komnenić 23 Jan '18

23 Jan '18

Dear FreeSurfer experts, I am trying to perform hippocampal subfield segmentation with FreeSurfer 6. I followed the instructions found on this page: https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfields which said that I first need to download Matlab Runtime. Which brought me to this page: https://surfer.nmr.mgh.harvard.edu/fswiki/MatlabRuntime I reach the stage where I type in curl "https://surfer.nmr.mgh.harvard.edu/fswiki/MatlabRuntime?action=AttachFile&d…" -o "runtime.tar.gz" after which I receive the following: Die Anwendung »curl« ist momentan nicht installiert. Sie können sie durch folgende Eingabe installieren: sudo apt-get install curl (my computer is in German, it basically says that curl is not installed and that I can install it via apt-get command). When I then type in that command and give my password, I receive: Paketlisten werden gelesen... Fertig Abhängigkeitsbaum wird aufgebaut Status-Informationen einlesen... Fertig Paket curl ist nicht verfügbar, wird aber von einem anderen Paket referenziert. Das kann heißen, dass das Paket fehlt, dass es veraltet ist oder nur aus einer anderen Quelle verfügbar ist. E: Paket curl hat keinen Installationskandidaten Which roughly translates to: reading package lists... done building a dependency tree reading status information... done Package curl is not available, but is referred to by another package. This could mean that the package is missing, outdated or available only from a different source. E: Package curl has no installation candidates. I would be grateful for any solution suggestions! Best, Darko

Re: [Freesurfer] recon-all error
by Bruce Fischl 23 Jan '18

we don't have much experience with it. Can you cc the FS list so that others can answer? I'll do so on this email. Maybe try some other tool for conversion? If recon-all fails it is not surprising that mri_convert also fails since they use the same DICOM code cheers Bruce On Tue, 23 Jan 2018, Julia Ströhlein wrote: > > Hi Bruce, > > thank you very much for your reply. > > > > I’m sure that I use the right series.

Re: [Freesurfer] [Re] medial wall label in Freesurfer 6

Yes, it solves medial_wall label problem but not mri_aparc2aseg error.log. I attached you in a previous message: https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg56610.html Many thanks, M del Mar

Re: [Freesurfer] MRI protocol for hippocampal subfield segmentation
by Gabor Perlaki 23 Jan '18

23 Jan '18

Dear Iglesias, Do you think that it is useful to also use a fieldmap for hippocampal subfield segmentation? Can Freesurfer's hippocampal subfield segmentation use it? I'm not sure that due to the limited resolution of the fieldmap and due to registration issues it is worth to acquire a fieldmap for hippocampal subfield segmentation. What do you think? Best, Gabor

Inquiry about process time by use "recon-all"
by Ritthikrai Thaweecharoen 23 Jan '18

23 Jan '18

Dear FreeSurfer Staff, We have conducted a brain volume study in normal Thai elderly. We found that the process time to analyze the brain of 20% of our subject took over 40 hours. The maximum process time is 99 hours. Eventhough the size of imaging file is around 20 MB and use “recon -all” command to process file. It would be grateful if you could help to explain tedious process time of FreeSurfer and how to shorten this process time. Our Machine spec. is as following: • INTEL i5 – 4260U CPU(a)1.4GHz • RAM 8 MB • Cent OS 6.x Best Regards Ritthikrai Thaweecharoen Data Scientist Research and Development Department Tel: 02 755 1919 Email Disclaimer : The information contained in this electronic mail message may be confidential and protected information intended only for the use of the entity name above.

freesurfer bids app cannot find license file
by Dianne Patterson 22 Jan '18

22 Jan '18

After trying the example bids app (which worked fine), I am trying the freesurfer bids app: https://github.com/BIDS-Apps/freesurfer I have built the docker container on my mac and I have the ds005 data directory here and the license.txt which I requested from freesurfer. I asked for a linux license (assuming the container contains linux and that was the relevant fact). dpat@Saci:/Volumes/Main/Working/BIDS_TESTING% docker run -ti --rm -v /Volumes/Main/Working/BIDS_TESTING/ds005:/bids_dataset:ro -v /Volumes/Main/Working/BIDS_TESTING/outputs:/outputs bids/freesurfer /bids_dataset /outputs participant --license_file "license.txt" 1: You should define 'SliceTiming' for this file.

Re: [Freesurfer] TRACULA QC
by Yendiki, Anastasia 22 Jan '18

22 Jan '18

Hi Linnea – Before the stats are computed, the probability distribution of the paths is thresholded to 20% of its peak value, so voxels with very low probability will not affect the outcome. Best, a.y From: <freesurfer-bounces(a)nmr.mgh.harvard.edu<mailto:freesurfer-bounces@nmr.mgh.harvard.edu>> on behalf of Linnea Marie Dramdal Borg <lmborg(a)stud.ntnu.no<mailto:lmborg@stud.ntnu.no>> Reply-To: Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu<mailto:freesurfer@nmr.mgh.harvard.edu>> Date: Monday, January 22, 2018 at 10:26 AM To: "freesurfer(a)nmr.mgh.harvard.edu<mailto:freesurfer@nmr.mgh.harvard.edu>" <freesurfer(a)nmr.mgh.harvard.edu<mailto:freesurfer@nmr.mgh.harvard.edu>> Subject: [Freesurfer] TRACULA QC Hi, We have run into some issues with our tractographies. I have attached examples: In "fmajor_4053.png", there is a "bridge" in forceps minor on its way to the frontal lobe. We've also come across other cases of bridging in forceps minor, such as "fminor_4013". Also, there are some voxel paths that are rather weak, such as "unc_2068_1.png" and "unc_3022_1.png"/"unc_3022_2.png". This does not seem optimal. Do you agree? We've also come across a couple of cases where it hasn't really found the tract correctly, such as in "29_ccg_1", "unc_3045_1.png" and "268_ccg.png". This also includes "fmm_32.png", which has a nice voxel intensity, but neither the forceps minor nor major voxels really fit their underlying tracts. Finally, neither "unc_3068_2.png" nor "unc_4040.png" are really correct. Should we reinitialize all of them, or can we use some of them without affecting the results too much? Thank you, Linnea Marie
