Hi Krish, I am afraid we had no joy with either option. No one in lab can get access, we have used both Mozilla Firefox, and Internet Explorer, neither can establish a connection. We never had a problem before. I have tried making changes to my computer firewall, again no joy. Liat -

Perhaps it is a DNS issue? You could try bypassing DNS by replacing the hostname with the ip in the URL: http://132.183.202.158/fswiki or https://132.183.202.158/fswiki If that works, then the problem is likely with DNS at Cornell, in which case you'll need to contact your network helpdesk.

Hi Giovonni, it stopped after detecting an unlikely transform, so no surfaces were created. You could run recon-all -s patient_lyp -all -notal-check which will skip the checking of the talairach xform, but if it is really wrong then things may feel. You can still use tkregister2 to do the

Thank you, Doug. This is good to know. Is this a general rule? As in, in general, is it bad to change the orientation unless it's incorrect? If it is not, what would be an appropriate tool to use in conjunction with mri_convert to perform this operation? *edit* Searching the archives, I fou

Marlisa, The memory ( RAM) you have? My guess is if Freesurfer uses significant amount of swap, it becomes slow. Is it different from other 2 machines or the same order of magnitude? If time permits, could you send the "Hardware Overview" information? ( Apple Icon in menubar->About this M

Hi Krish, So all the machines have 4 GB of memory. However, the faster machine has 6 (4 x 512MB, 2 x1GB), whereas the slower ones are 1GB in 4. Possibly that's the bottleneck. All are 667 MHz regardless of machine. I'm thinking this could be the issue. Marlisa > Marlisa, > > The memory ( RAM) y

[Freesurfer] green lines in tkregister2

Hi, I started to use Freesufer and finished the first step of recon-all. When I checked the talairach transform, the tutorial said there should be green lines which can be turned on or off by clicking the image window and hitting the s key. But it didn't work for me. Is this because the g

[Freesurfer] qdec color scale

Hello Surfers, I just wanted to confirm what I am interpreting in some analysis in qdec. Some fellow techs here are running qdec on a group of controls, TBI and PTSD subjects and are trying to figure out what exactly the color scale is telling us. From the mail archive I understand that the blue

Yes, the green lines are the surface, so if you don't have a surface, you won't see green lines. You should that the volumes "line up". For talairach, this is to mostly make sure that the edges of the brains are about the same place and that the orientations are about the same. doug karlkarl w

Sky, Yes, your assumption is correct. The colors are relative to the first variable in the description, as you have described. As a side note, the .levels file is not strictly necessary (thats the file that specifies your discrete factor names), since the loader will figure out discrete factors
