error while loading shared libraries:libtiff.so.3
by lan lin 13 Aug '08

13 Aug '08

I'm using 64 bit Ubuntu and installed freesurfer-Linux-rh9-stable-pub-v4.0.5-full.tar.gz<ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer-Linux-rh9-stable-pub-v…> Everything worked fine when I tested the installation with tkmedit and tksurfer. I then ran recon-all and got error message while loading shared libraries:libtiff.so.3. I have tried ln /usr/lib/libtiff.so.4 /usr/lib/libtiff.so.3 But still got same error message.

FDR button
by Juergen Haenggi 13 Aug '08

13 Aug '08

Dear FS experts When using the FDR button in the Configure Overlay Display, there appear the FDR corrected new threshold in the terminal after pressing the Set Threshold Using FDR button. However, when changing the rate from 0.05 to e.g. 0.1, the FDR corrected threshold does not change. Why? Furthermore, this threshold is different when the sig.mgz will be truncated. What does mean the option Only marked? Thanks in advance Best regards Juergen ----------------------------------------------------------- Juergen Haenggi Ph.D. (Dr. des.)

cortical thickness
by 李日 13 Aug '08

13 Aug '08

Hello, I am new to freesurfer, I used recon-all and it finished, I can get the thickness map,and i have some questions about the tksurfer tools. I paste a picture of the tksurfer tool window in the accessory,and i have labeled 3 areas. In area 1, I think is the thickness information, what does the number 3.274984 mean? In area 3, what is the funtion of the red and green line? Best Regards.

cortical thickness for a ROI
by Deniz KATIRCIOGLU 12 Aug '08

12 Aug '08

Hi, I want to learn if there exists a way of overlaying the "cortical thickness output" of "recon-all -*autorecon3*" stage with a ROI drawing (a 3D image file with non-zero values for ROI and zero for the remaining parts) performed in AFNI, so that we can better restrict the cortical thickness to our specific region to extract the thickness information around there, locally. Thanks in advance... Deniz KATIRCIOGLU METU, Turkey

cortical thickness at different locations
by Al-Radaideh Ali 11 Aug '08

11 Aug '08

Hi, I managed to measure the cortical thickness for different subjects and to display their maps. Bu t I am not sure if I can measure the cortical thickness at some points in the cortex or at least the cortical thickness for some cortical regions.

longitudinal stuff
by Sky Raptentsetsang 11 Aug '08

11 Aug '08

Hi Bruce, From the processing that's been performed we're fairly certain that the issue is only with the -long script. So I just wanted to verify with you if I processed our many baseline subjects with version4 (cross-sectionally), while the -long script is being bug-fixed, I could simply start the subjects longitudinal scans once your fix is in place. So from your investigations thus far, could you tell us if the FSv4 cross-sectional processing will be altered due to any fix that might be put into place in the near future? Many thanks as always! Cheers, Sky
