Automation
All of the steps below are contained in the scripts file /Volumes/data9/surface/scripts/@recon
To run this command type,
/Volumes/data9/surfaces/scripts/@recon ec subjname
Where ec is the two-letter experiment code and subjname is the subject's name in the format lastname_firstname. The scripts assumes that all of the steps performed the script file @prep_dir have been performed (see Preparation for Creating Cortical Surface Models page) e.g.
/Volumes/data9/surfaces/scripts/@recon BD doe_jane
Running FreeSurfer
The cortical surface reconstruction program recon-all has many options for processing the files, which are listed on the wiki: https://surfer.nmr.mgh.harvard.edu/fswiki/recon_2dall The easiest option is to run the entire file stream with the following command:
recon-all –all –s subjID
Often this will result in errors because FreeSurfer has permissions issues when copying and appending files. Processor usage can be checked using the program top in another window. If recon-all has been running one subprogram for an inordinate amount of time you can kill it using ctrl-c from the window where you are running recon-all. Reset the permissions so everyone can read and write files from the subject’s directory:
sudo chmod –R 777 $SUBJECTS_DIR/subjID
After resetting the permissions you should check where the program crashed by viewing recon-all-status.log in the subject’s scripts folder. Check the FreeSurfer wiki on how to restart the file stream from where the program crashed. For example, if the program during CA Normalize the program can be restarted using the following line:
recon-all –nogcareg –autorecon2 –autorecon3 –s subjID
Since the all the Macs in the lab are multiprocessor machines, the program can delegate each hemisphere to a single processor. To do this recon-all first needs to preprocess the anatomical data and then identify the white matter:
recon-all -autorecon1 -s subjID recon-all -autorecon2 -s subjID -notessellate -nosmooth1 -noinflate1 -noqsphere -nofix -nofinalsurfs -nosmooth2 -noinflate2 –nocortribbon
After the white matter has been defined, recon-all can process the two hemispheres separately using separate log and status files:
recon-all -s subjID -hemi lh -log $SUBJECTS_DIR/subjID/scripts/recon-all_lh.log -status $SUBJECTS_DIR/subjID/scripts/recon-all-status_lh.log -tessellate -smooth1 -inflate1 -qsphere -fix -finalsurfs -smooth2 -inflate2 -cortribbon -autorecon3 &; recon-all -s subjID -hemi rh -log $SUBJECTS_DIR/subjID/scripts/recon-all_rh.log -status $SUBJECTS_DIR/subjID/scripts/recon-all-status_rh.log -tessellate -smooth1 -inflate1 -qsphere -fix -finalsurfs -smooth2 -inflate2 -cortribbon -autorecon3
Alternatively you can use the script in the surfaces folder, which runs recon-all in the manner described above:
/surfaces/@recon-all_sep_hemi –subj subjID
Be forewarned that use of this script on the iMacs will hamper system performance when the two hemispheres are simultaneously processed.
Using FreeSurfer on Another Mac To Speed Up Surface Creation
Some Macs have multiple processors and faster CPUs, making them better for surface creation. The fastest Mac in the lab is currently Mike Disano's MacPro. To create a surface on this Mac:
ssh mbeauchamp@139.52.6.5 cd mount mkdir data9 mount_afp -i afp://mbeauchamp@129.106.236.180/data9 data9
enter password
~/mount/data9/surfaces/scripts/@recon_remote EI maili_lorena
It is easier to do the @prep_dir and @finish scripts on your local machine since they run quickly.
Changing the Default Shell and othe tidbits
Remember to change the default shell for the super user:
chsh –s /bin/tcsh
Now you should be able to edit any file like you would do from the iMac. To enable window forwarding so that you can open GUIs like afni remotely you’ll need to take the following steps:
- Find your IP address using ifconfig. The address will be listed under the device en0, next to inet. For example in the following output the IP address is 129.106.326.192:
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet6 fe80::216:cbff:fe84:414a%en0 prefixlen 64 scopeid 0x4 inet 129.106.236.192 netmask 0xffffff00 broadcast 129.106.236.255 ether 00:16:cb:84:41:4a media: autoselect (1000baseT <full-duplex,flow-control>) status: active
- Allow your computer to accept window forwarding from the PowerMac:
xhost +129.106.236.16
- From the window that is logged onto the PowerMac set the display IP address:
set DISPLAY = 129.106.236.192:0.0
To exit enter exit twice (once to exit from being a super user and another time to exit from the remote login.
