Quinn,

Could be that the table has any strange character in it (e.g. strange white space etc. ) 

Try to create a table in a simple text editor by typing the header line and the first 1 or two rows (space separated). If it can read that, then it is probably the format of your table. 

Best, Martin

Dear Freesurfer team, 

I am trying to perform qdec longitudinal analysis. 
I have ran produced the template and long files, as well as the longitudinal table. 
 
I am currently trying to perform the long_mis_slopes command however I keep getting:
ERROR: qdec table /qdec/long.qdec.respsex.table.dat not found or empty?

I am using 
Freesurfer version: freesurfer-Darwin-lion-stable-pub-v5.3.0  
Platform: OS X El Capitan


The table does exist, however, I keep getting the same error. The table has the columns that are specified as being necessary (fsid, fsid-base, and an age column - "days" in my case). Currently it also has a response and sex column. I have changed the age column to "years", changed the location in/out of my subjects folder into a 'qdec' folder within /subjects. I removed the fsid column and received an error output of 
ERROR: qdec table missing correct column headers?
       Make sure first column is labeled 'fsid' for the time point and
       second column is 'fsid-base' to specify the subject tempate (base), e.g.:

 fsid    fsid-base   age 
 me1     me          22.3 
 me2     me          23.2 
 you1    you         21.6 
 you2    you         22.5

suggesting that it can see the .dat table. Additionally, from the terminal I can open the table in microsoft excel, pico etc.
However, it fails when it tries to parse the table. 

I have attached a log of the varying attempts I have made to use the long_mris_slopes command. 
I have also attached what is essentially the .dat table I have been trying to use for your viewing as well. 
I've searched the list and can't seem to find discussion of this error with regards to the long_mis_slopes command. 
Am I missing something? 
Does anyone have any thoughts on how to trouble shoot this? 

Thank you. 

Quinn
