Good morning -
I am exploring the human connectome dataset with AFNI, doing standard seed-based connectivity to try to replicate some studies RSFC out there. At the end I'm using 3dttest++ to display some ttests vs. zero for my seed of interest, while I'm attempting to covary for age and gender.
My 3dttest++ script file is set up like so:
100307 /Volumes/Faraday/DATA/DBS_RSFC/100307/R_vent.100307.Z+tlrc \
100408 /Volumes/Faraday/DATA/DBS_RSFC/100408/R_vent.100408.Z+tlrc \
101006 /Volumes/Faraday/DATA/DBS_RSFC/101006/R_vent.101006.Z+tlrc \ (&etc again, n = 496)
My covariates file is set up like so:
subject age gender
100307 27 1
100408 33 0
101006 35 1 (&etc)
And I am getting the following error:
++ 3dttest++: AFNI version=AFNI_2011_12_21_1014 (Nov 2 2015) [64-bit]
++ Authored by: The Bob++
++ 217793 voxels in -mask dataset
++ Covariates file: 3 columns, each with 496 rows

++ loading covariates
100408' in covariates file '
101006' in covariates file '
101107' in covariates file '
(&etc through all 496 participants of interest)
I've used identical set ups with prior analyses with no issues, never seen the above error previously. Is it possible 3dttest++ is unable to read 496 rows, even though there are only two covariates? Or, is there another error here I've missed?
Any input is appreciated!
