norm.mgz

Hi, I am using recon-all and the norm.mgz's so far are only about half the brain. I checked the input volumes and looked though the output to std and everything seemed fine, so I am not sure what to do: on machine vader source /usr/local/freesurfer/nmr-std-env setenv SUBJECTS_DIR /autofs/space/boba_001/users/nrecon/ which mri_ca_normalize /usr/local/freesurfer/stable/bin//mri_ca_normalize cd /autofs/space/boba_001/users/nrecon/ARSS70_nrecon/mri mri_ca_normalize -mask brainmask.mgz nu.mgz /usr/local/freesurfer/stable/average/RB_all_2006-02-15.gca transforms/talairach.lta norm.mgz output: using MR volume brainmask.mgz to mask input volume... reading 1 input volumes reading atlas from '/usr/local/freesurfer/stable/average/RB_all_2006-02-15.gca'... setting gca type = Normal gca type reading transform from 'transforms/talairach.lta'... reading input volume from nu.mgz...

Re: [martinos-tech] FreeSurfer NIFTI with SPM and AFNI
by Doug Greve 23 Mar '06

23 Mar '06

I've just fixed a bug in the way FreeSurfer produces *uncompressed* NIFTI files. It actually always produced *compressed* files, even if the extetion was just .nii and not .nii.gz. I have fixed this, and it will be live in dev tomorrow and live in stable at the next update. I've successfully loaded uncompressed files into both SPM and AFNI, but failed on compressed. Does anyone know if they even can read compressed? Both compressed and uncompressed work with FSL. doug -- Douglas N.

still trouble with this motioncor problem

Hi I emailed a little while ago about this, but I haven't heard any solutions yet. As a check, I re-ran recon-all again this morning on a local machine. Still crashing.

recon-all bug in -normalization2 ?
by skenny＠uchicago.edu 23 Mar '06

23 Mar '06

hi all, i noticed this bug in the recon-all script. according to the reconAllDevTable, if recon-all is called with just the -normalization2 flag it should call both mri_normalize and mri_mask. however, in looking at the script it seems to only call mri_normalize. so, if using that flag you should be aware that it will not call both processes and brain.finalsurfs.mgz will not be produced. this issue came up as i was working on parallelizing; but it was pointed out to me that this info would be useful to others as well, so i'm starting a new thread. the solution i used was to change the recon-all script so that it calls both processes with that flag...or you could just explicitly call mri_mask on the commandline after you've run recon-all with the -normalization2 flag. sarah

mri_convert problems

Re: [Freesurfer] Faster and Parallel recon-all

hi there, i'm actually working on parallelizing recon-all on a grid...i *think* the script won't work all the way thru bcs calling recon-all with the -normalization2 flag is supposed to call both mri_normalize AND mri_mask (according to the DevTable); but it looks as if the recon-all script only calls mri_normalize with that flag...this means mri_mask is never called and brain.finalsurfs.mgz is not produced...so when you get to -finalsurfs it can't find the file...alas i just changed the recon-all script to call mri_mask when it gets the -norm2 flag...this seems to have worked. sarah ---- Original message ---- >Date: Wed, 22 Mar 2006 18:09:11 -0500 >From: Daniel Goldenholz <daniel(a)nmr.mgh.harvard.edu> >Subject: Re: [Freesurfer] Faster and Parallel recon-all >To: "Goradia, Dhruman D" <goradiadd(a)upmc.edu> >Cc: freesurfer(a)nmr.mgh.harvard.edu > >Hi again, > >I have totally revamped the script in light of the fact that recon-all >-notify did not do what I thought it did at all! >The new and improved (version 1.02) super-recon is quite a bit fancier. >Now, I leave all notifcations and waiting and emailing to super-recon >itself, so that recon-all assumptions are reduced. > >If you want to run a complete recon-all -all but have the hemisphere >parts run in parallel, you run a command like this one: >super_recon all $SUBJECTS_DIR $SUBJECT /space/dicom/file1 >/space/dicom/file2 my_email(a)wherever.nmr.com > >Using this new and improved command, if you have a cluster with daul >processors, then you should be able to run multiple >subjects faster than a standard recon-all command. > > >The script in "all" mode will run the same stuff as recon- all -all. >If you wish to run a subset of the full set of commands, you can simply >comment out a specific line you don't want. >There are also several other ways to call the script now, since in >reality it calls itself recursively with different options. > >Hopefully this one will do what the original one intended to do. >Good luck, >Daniel > >Goradia, Dhruman D wrote: > >>Hi Daniel, >>The script is ok but it still does not make it to the end.

Re: [Freesurfer] mri_convert problems

Hi Inge, > When trying to convert some new scans with mri_convert there seems to be a > problem with the reconstruction, also the signal intensity is in the > 300-500 range. See attached image. It does not return any errors. > > Could someone please point me in the right direction here? The log say's that it has found 130 dcm files, which is two files too much for a 128slice sequence, as nICE is saying. So, perhaps there is something in the folder, which should not be there, even though mri_convert also detectes that the sequence had originally 128 slices, but this might have produced this offset in the images. How does the volume look likes, when you are looding it into nICE?

--conform option
by Pellegrini, Stefano (NIH/NINDS) [F] 23 Mar '06

23 Mar '06

Hi everybody, can anybody explain to me why when I use mri_convert with the --conform option with an input volume RAS oriented (let's say it is raw_mean.mgz) I get as output a volume LIA oriented (let's say it is orig.mgz)? is that ok? thanks, -stefano
