job opportunity
by Paige Scalf 25 May '11

25 May '11

Beginning August 15th, a two-year position is available for a highly motivated and talented postdoctoral fellow in the Department of Psychology at the University of Arizona. The goal of this research program is to study the neural processes that support vision, perception and attention using functional neuoimaging (including ultra high resolution and time resolved fMRI) and behavioral (including eye-tracking) methods. Candidates will be expected to support the research goals of the PI, but will also be given the opportunity to develop more independent lines of research. The candidate will be encouraged to take advantage of the highly collaborative departmental environment. The Department of Psychology is part of the School of Mind, Brain, and Behavior (MBB), and is a member of the College of Science, in keeping with its strong research-oriented approach and scientifically-derived knowledge base. Its faculty and students interact and collaborate with those of other MBB programs and departments—Neuroscience, Cognitive Science, and Speech, Language and Hearing Science—as well as with other academic units across campus. The fMRI facilities at the University of Arizona includes a GE 3.0T Signa scanner that is fully available for research use 5 days per week. The University of Arizona is a premier (NSF ranking: # 16) public research university located in Tucson, Arizona. The sun shines nearly every day in Tucson, which is surrounded by four mountain ranges that include the southernmost downhill ski resort in the USA. Tucson also supports great opportunities for hiking and cycling, and is one of the most bicycle friendly cities in the US. Candidates must have a PhD in neuroscience or a related field and the capacity to make a substantive intellectual contribution to the research program. Candidates with previous neuroimaging experience and strong programming skills will will be preferred. Of particular interest are those candidates with experience using python-based programs such as the Vision Egg and SciPy. For more information, contact Dr. Paige Scalf (pscalf(a)gmail.com) Applications may be submitted to job #47659 at http://www.uacareertrack.com.

flattened patch ascii file & matlab
by Cris Lanting 25 May '11

25 May '11

Dear all, I'm trying to read a flattened patch (ascii) using matlab but I'm slightly confused: after performing mris_flatten and mris_convert -p rh.patch.flat rh.patch.flat.asc I get the following file: #!ascii version of patch ./rh.orig. The 1st index is not a vertex number 12755 25052 -46888 vno=46887 -47.306606 -24.583883 0.000000 -46894 vno=46893 -44.649334 -26.691339 0.000000 ... 94637 48206 48190 46887 94661 48221 48205 46896 And based on the read_patch script (freesurfer_dir/matlab) I'm able to extract the vertices and faces. vertices_flatmap: -47.3066 -24.5839 0 -44.6493 -26.6913 0 -45.1151 -25.9817 0 ... & faces_flatmap 48206 48190 46887 48221 48205 46896 46893 48218 48219 ... Yet, if I call Hpa = patch('vertices',vert_flat,'faces',face_flat,... 'EdgeColor',edgecolor,'FaceColor',facecolor); it comes up with an error: Warning: Values in patch Faces must be in [1 : rows(Vertices)] - not rendering. I suppose this relates to the fact that it is a subset of the actual complete surface and that it therefore does not start with index 1 (but 48206 instead). Any suggestions how to proceed from here? In the end, I'd like to visualise an overlay (saved as .w file) onto the flattened patch instead of on the inflated surface. Kind regards and thanks in advance, Cris Lanting

Re: [Freesurfer] temporal pole label
by Bruce Fischl 25 May '11

the easiest thing to do is to convert all the annotations to labels, then just use the temporal pole one. I don't think there is an option at the moment to only extract a single label, but Doug will correct me if I'm wrong :) cheers Bruce On Wed, 25 May 2011 kwa1(a)rice.edu wrote: > Dear Bruce, > > Thanks for the prompt response again.

Hi Kareen, I'll cc the list as others may be interested. You can use mri_annotation2label to extract the label you want. As for which to use, it depends what you want to do with it, but I would expect the individual labels are what you want since they are adjusted to account for individual variations in the anatomy. cheers Bruce On Wed, 25 May 2011 kwa1(a)rice.edu wrote: > Dear Bruce, > > How can I access these temporal pole labels within each subject?

temporal pole label
by kwa1＠rice.edu 25 May '11

25 May '11

Hello, I have a question about the labeling in tksurfer. My goal is to take an average inflated surface of 10 controls and then make a temporal pole label out of that average. Alternatively, if FS provides a label for the TP for each patient I could average the labels together. Do you have any idea how best to do this? Thanks in advance. Warm regards, Kareem

overlay properties tksurfer window incomplete...
by Gonzalo Rojas Costa 25 May '11

25 May '11

Hi: I have an ubuntu based computer with Freesurfer 5, and it seems that because the font size or the screen resolution, the lowest part of the "Overlay Properties" window in tksurfer didn't appears (Ok and Cancel buttons, for example, etc)... Any solution ?... Sincerely, Gonzalo Rojas Costa Laboratory for Advanced Medical Image Processing Department of Radiology Las Condes Clinic Lo Fontecilla 441, Las Condes, Santiago, Chile.
