optseq2 parameters setup

External Email - Use Caution Hi Dr. Greve, I am interested in designing the Face Name Associative Memory Exam (FNAME) fMRI task for our study. There are 80 face-name pairs that we will use and the duration can be between 3.5 and 4.75 secs. I have used the following command: optseq2 --ntp 200 --tr 2 --psdwin 0 32 2 --ev facename 4 80 --nkeep 3 --o trial2 --tnullmin 0 --tnullmax 6 --nsearch 10000 Total scan time appx 6-7 mins. Q1: For NULL, why do we have only 2 sec and 4 sec jitters? Can we change the variety amount of the jitters? Are more jitters good or bad (instead of just having 2 secs and 4 secs, let's say we get 0.25, 1, 2, 3 and 4 secs) ? Q2: For the event design I am interested in above, what would be the "best" parameters used? Trial2-001.par: 0.0000 1 4.000 1.0000 facename 4.0000 1 4.000 1.0000 facename 8.0000 1 4.000 1.0000 facename 12.0000 0 2.000 1.0000 NULL 14.0000 1 4.000 1.0000 facename 18.0000 1 4.000 1.0000 facename 22.0000 1 4.000 1.0000 facename 26.0000 1 4.000 1.0000 facename 30.0000 1 4.000 1.0000 facename 34.0000 1 4.000 1.0000 facename 38.0000 1 4.000 1.0000 facename 42.0000 0 4.000 1.0000 NULL 46.0000 1 4.000 1.0000 facename 50.0000 1 4.000 1.0000 facename 54.0000 1 4.000 1.0000 facename 58.0000 1 4.000 1.0000 facename 62.0000 1 4.000 1.0000 facename 66.0000 1 4.000 1.0000 facename 70.0000 1 4.000 1.0000 facename 74.0000 0 2.000 1.0000 NULL 76.0000 1 4.000 1.0000 facename 80.0000 0 2.000 1.0000 NULL 82.0000 1 4.000 1.0000 facename . . . . 372.0000 0 4.000 1.0000 NULL 376.0000 1 4.000 1.0000 facename 380.0000 1 4.000 1.0000 facename 384.0000 1 4.000 1.0000 facename 388.0000 1 4.000 1.0000 facename 392.0000 1 4.000 1.0000 facename 396.0000 1 4.000 1.0000 facename Thank you in advance!

Re: [Freesurfer] general installation and configuration questions (new user!)

External Email - Use Caution Hello Robin, I believe folks use the freesurfer binary archive expanded/installed on file servers that are remotely mounted, e.g., thru NFS, so everyone can share a common installation.  IT/dev-ops can implement that in different ways, e.g., maybe the freesurfer installation actually lives on a fast RAID/redundant file system over NFS, etc.  But you ultimately need to set FREESURFER_HOME in your shell environment point to wherever freesurfer is installed which could be a remote mount point on your local computers file system.  Hopefully a remote mount point to the freesurfer installation (via NFS) is standardized to be the same path for everyone on their local machines. Fast disks and fast filesystems can always help with speeding up read/writes of data.  SSD storage hanging off the latest PCIe buss designs should outperform hard drives. Users often have a local disk in their machine to process data (preferably not the same disk as the boot partition is on).  Or maybe IT has some available storage over NFS for users to process their data, though read/writes over NFS are going to be slower than working off a local disk (with or w/o -openmp).   You could use soft links to point to different parts of the data if you wanted to physically re-locate pieces of it, but any paths thru soft links should make it look like there is a single tree with the data. - R.

Create no-skull brain with gray matter mask
by Marina Fernández 15 Jul '19

15 Jul '19

External Email - Use Caution Dear experts, I need to get a no-skull brain. The automated no-skull brain has many errors and I was thinking that I could create it taking into account the gray matter mask (we segment manually, so the mask is accurate) in such a way that everything outside the gray matter mask is eliminated and everything inside is maintained. Do you know how can I create it? Any idea will be welcome. Thank you very much. Best regards, Marina.

CSF mask
by Laboratorio de Neurociencia Funcional 15 Jul '19

15 Jul '19

External Email - Use Caution Dear Freesurfer experts, Is there any way to obtain a CSF mask in Freesurfer similar to that obtained with the SPM segmentation (see attached file)? I would need that the CSF mask contains not only the cerebral ventricles but also the extracerebral CSF. Any help with this would be greatly appreciated. Best regards, Jose

general installation and configuration questions (new user!)
by Robin Warne 15 Jul '19

15 Jul '19

External Email - Use Caution Hi folks, I am new to the Freesurfer world and I have a couple of questions about installing the application, specifically around the 10Gb "footprint" of data, after unpacking the archive file. So I have run through the installation and configuration steps outlined on the Wiki page, which is great, by the way! Running through the steps first time around went without a hitch but the conversion of the sample data took many hours. If I have to run that conversion again, I will try the recon-all with " -openmp { some appropriate value } " to try and speed it up. I'm guessing that the sample data is occupying a large part of the 10Gb disk space "footprint" so is it appropriate to remove it, without breaking anything? If we wanted to install Freesurfer on to a server, for multiple users to access, is that possible? Somewhere like '/usr/local', as described in the Wiki? Thanks in advance, for any guidance anyone can offer. Robin Warne, University of Kent (U.K.)
