OK your structure is correct,
there are a few things to test next. Let's take this offline until we know what's going on and then post the result to the list to avoid spamming everyone.

Dear Martin,

yes the subject directory setup is correct. I suppose that otherwise “generate stats data tables” in qdec also wouldn’t work which isn’t the case. The QDEC_Final directory includes two time points for each patient, the patients base, the “long” folders that were created for each patient’s time points and the “qdec” folder.  The “.Qdecrc” file is inside of the qdec folder. Should there also be a folder named “Qdecrc” in the qdec folder or really just the “.Qdecrc” file?  Or do I have to create a folder named “qdec/.Qdecrc” in my “QDEC_Final” folder?

I suppose I don´t have to type “$SUBJECTS_DIR/qdec/.Qdecrc” in the shell I am working in before starting qdec.

I am awfully sorry for asking so many stupid questions but I ran out of things I could try.

Thanks a lot once again!

Best regards

Peter

Is your environment variable ($SUBJECTS_DIR) setup correctly? It needs to point to where the subjects and the qdec directory are.

so you should have a dir structure like this inside your subjects dir (QDEC_Final):

subject1_tp1
subject1_tp2
...
qdec/.Qdecrc
that is the same as:
$SUBJECTS_DIR/qdec/.Qdecrc
if your environment variable is set correctly

Dear Martin,

I tried adding another line in the file which didn´t change anything. My subject directory is called “QDEC_Final” and in that directory I created the “qdec” folder which includes the tables and also the”.Qdecrc” file. The file is definitely there and can be listed by using “ls -a”.
So I suppose there shouldn´t be any mistakes so far. I created the .Qdecrc file by opening a new text file, writing down the four lines and saving it under the name “.Qdecrc” afterwards. While saving it I used the default UTF-8 encoding in Kwrite.

Still there seems to be the Problem that qdec can´t find the .Qdecrc file.
Do you still have any other idea as for what to try? Would renaming the files in the base directory be an solution or would that lead to many other problems?

Thanks a lot!

Best regards

Hi Peter,

file looks good, you could try adding a newline at the end. The file should be hidden (all files starting with a . are hidden). Not sure why you cannot select the rate as the measure. Is your environment variable ($SUBJECTS_DIR) setup correctly?

Dear Martin,

”thickness” was a typo. Can you maybe check my attached file? I suppose that I put the four lines in it correctly. I only named it “.Qdecrc”. When I save the file in the qdec folder of my Subject directory, the file isn´t visible anymore. Is it supposed to be like that? It is there but not visible. Furthermore I can´t chose e.g. long.thickness-rate in the Design Tab.

Thank you very much and I am sorry for bothering you so much.

Best regards

Peter

Hi Peter,

it needs to be .Qdecrc and have these lines:
MEASURE1 = long.thickness-avg
MEASURE2 = long.thickness-rate
MEASURE3 = long.thickness-pc1
MEASURE4 = long.thickness-spc
You will then see in the Design tab in Qdec, that you can now select e.g. long.thickness-rate under Measure as the dependent variable.

You wrote below that you get this error:
"couldn’t open…/1CAGB/surf/lh.thikness.fwhm10/fsaverage.mgz or .mgh file"
note that thickness is spelled with 'ck'. Check your .Qdecrc if there's a typo.

Dear Freesurfer experts,

 

Or could it be that I made a mistake creating the “Qdecrc” file?
I simply created a text file in the qdec directory and named it “$SUBJECTS_DIR/qdec/.Qdecrc” and put the four lines in it as advised. Should it just be named “.Qdecr” or is there supposed to be an empty line somewhere in the file?

Thanks a lot!

Subject: Re: [Freesurfer] long_mris_slopes/long_qdec_table command not found

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.

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!

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 type
freesurfer
into the terminal window? It should print the version.

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

Peter
