I'm getting an error when trying to run 3dDetrend on time series data. I got the following error:
++ 3dDetrend: AFNI version=AFNI_16.0.10 (Feb 25 2016) [64-bit]
*** Illegal inputs to startup_lsqfit
** FATAL ERROR: Choleski factorization fails: linearly dependent vectors!
this is my 3dDetrend call:
3dDetrend -polort 1 -prefix detrend_run1_101_RHead_Sub run1_101_RHead_Sub.1D
My input time series is one column. It looks like
this. I'm not sure what the issue is.
