Dear Freesurfer experts,
thanks to your help I was able to install the new version and run the „long_mris_slopes“ command. In the next step I shrank the longitudinal QDEC table into the cross sectional form by using “long_qdec_table” which also worked so far. Loading that table into QDEC and generating stats data table is no problem but afterwards, when I try to analyze the data in the “Design” section, I received an error message. It always says “couldn’t open…/1CAGB/surf/lh.thikness.fwhm10/fsaverage.mgz or .mgh file”.
As an additional explanation for this example:
1CAGB is the base for the first time point CA and the second time point GB. Files with the wanted name exist in the surf directories of the two time points but not in the surf directory of the base. The closest thing in the base surf directory is called “lh.long.thikness.avg.fwhm10.mgh”.
Could it be that there is a mistake in the “cross.qdec.table.dat”? Just like in the manual for creating the “long.qdec.table.dat”, I listed all the single time points under fsid and the base under fsid-base.and created the cross table afterwards. But when I open the “cross.qdec.table.dat”, the base names (1CAGB etc. in this example) are listed under “fsid”.
Did I do something wrong during the creation of the long.qdec.table.dat or the cross.qdec.table.dat? Do you have any other explanation otherwise?
Thank you very much for your help!
Best regards
Peter Bohn

Not totally sure with 5.0, but I don't think it requires same voxel space for all time points (since 5.1), so it should work to run the analysis with 5.3 on that data.

Thanks a lot! Do I have to repeat creating the base and the longitudinal runs once I use the new version or are they compatible concerning this aspect?
Thank you very much!

Yes, those scripts are available since 5.2. You need to update to a newer version.

Hi Martin,
thanks a lot fort he quick reply! When I type freesurfer into the window it shows me v5.0.0 as the version. Sorry for my prior mistake concerning the version’s name. All other commands I use run perfectly fine.
Thanks once again!
Best regards
Peter

Hi Peter, can you run any free surfer command at all? Looks to me that you did not source free surfer. What happens if you typefreesurferinto the terminal window? It should print the version. Best, Martin On Jun 20, 2013, at 5:17 AM, Peter Bohn bohn-peter@gmx.de wrote:
Dear Freesurfer experts,
I was trying to run some longitudinal analysis but whenever I want to use the commands “long_mris_slopes” or “long_qdec_table” I just get “command not found” as an answer. When I try to look up a package that might include the command, by typing “cnf long_mris_slopes”, I also just get “command not found” as an answer. We are currently using version v 1.313.2.6.
Does anyone of you know if the two commands that I would like to run, are included in this version? Where would I have to look for the additional package if it exists? Or am I by any chance just typing the commands incorrect?
Many thanks for the help!
Sincerely yours
