Fix for mri_watershed
by Kevin Teich 14 Apr '04

14 Apr '04

There's a new version of mri_watershed available. The fix is to eliminate s problem with the WM value. The previous version sometimes used the pon area for the WM value.

mris_flatten usage
by Jonathan Polimeni 03 Apr '04

03 Apr '04

hello all! i have a fast question regarding the usage of mris_flatten: what are the available command line options? the usage message displayed by mris_flatten only lists the "-w" and "-distances" options, but i also know of the "-p" option, and there was an earlier posting that mentioned a "-s" option as well. does the option "-p <N>" repeat the flattening procedure N times by feeding the output of flattening k into the input of flattening k+1? does the "-s 1" option turn the scaling off? is this a binary flag? is the default then equivalent to passing "-s 0"? thanks in advance! -jon

Need help! In csurf when I click on volume or surface to display images the following error message arises the same thing happens if I try to use tkmedit/tksurfer from the command prompt. Error while loading share libraries: libtk8.3.so:cannot open shared object file: no such directory I cannot locate libtk8.3.so on my computer so I looked up RPMfind on the net a download is available but it leads to a broken link can anyone send me this library? >From the websearch I found that libtk8.3.so is part of a graphical toolkit TCL scripting language. Do I need to have TCL on my machine? Are there any other specific requirements to run Freesurfer? Many thanks Mary Fitzsimons

Looking for correct coordinates
by Daniel Goldenholz 31 Mar '04

Hi freesurfer folks. I have a pair of inflated brains that I'd like to work with in matlab. I found a nice function called "read_surf.m" which works very well. But I noticed that the two hemispheres cannot be viewed at the same time, because their locations overlap! I pushed one to the left and one to the right by an arbitrary amount, and this looked a bit better. But I was hoping to put the position of the inflated brain in the correct spot so that I could correlate MEG info with these surface files. What else do I need to know about positioning these brain surfaces? Thanks -- Daniel Goldenholz -----------------------------------------------------
