Cannot extract tract statistics for subjects from a connectometry database

[maximev...@hotmail.com]

Dear Frank,

Thank you so much for providing DSI_studio.

I have encountered an issue that I unfortunately cannot solve:

I have reconstructed a series of subject using QSDR, and I have created a connectometry database using [C2: Create a Connectometry Database] based on the reconstruction outputs. Since my data are 1.25 mm³ resolution, I changed the target template to the hcp1065_1mm.fib.gz. I then opened the database with [T3: Fiber Tracking], tracked some tracts, and tried to get the statistics of these tracts for all subjects from the database. However, when I click on 'Tracts -> Statistics', I get an output file with values for the first rows (e.g. number of tracts, mean length etc.) but when it reaches the values for each subject, I just have the name of the first subject from the database, and then a blank value, just like this:

...

gfa 0.0874818

iso 0.493854

mni_icbm152_t1_tal_nlin_asym_09c 207.985

mni_icbm152_wm_tal_nlin_asym_09c 0.745039

sub-020_eddy_corrected_data mean_qa

It doesn't work for any tracts. Do you have any idea of why it can't extract the QA values? 

I have done that in the past with another dataset, altough it was 2mm³ data, and it worked perfectly. I have uploaded the database file to your dropbox repository. 

Thank you in advance for your help and for providing support to this great software.

Best,

Sorry for the issue.

I will check the data and get back to you.

It is working nicely on my side. My suggestion: (1) update DSI Studio (2) try on a computer with a larger memory

Hope this works for you.

Dear Frank,

I updated from the August build to the most recent version (September, 22), and it now works well. 

Thank you for your help.
