Hi Group,

Has anyone encountered this error [see below] on a Mac before?  It occurs during step 5 / 7 when importing ROI Data.  I have traditionally used a windows machine and older versions of Matlab and CONN and have not encountered this error.......?

Any thoughts on the topic are much appreciated.

Best,

Matt

Dear Alfonso, 

I am encountering the same issue (I copied the error message below). I am processing my data in CONN v. 17, on Mac High Sierra. 
I have realignment, QA_timeseries and scrubbing as first level covariates.
I entered them using CONN GUI.
I checked the first level covariates in the subject where this error occured, and I don't see any NaNs ot Infs.

One precision regarding my current set up. A reviewer asked me to perform test-retest reliability measurements on my data set. I have only one resting state session so I decided to cut this session in half, enter the two halves into a new CONN project as session 1 and session 2, perform the first and second level analysis as in my initial project, and correlate the second level maps from the first and the second session. High correlations would implicate reliability. 
I have 200 volumes, so I cut in half the preprocessed (swauf*) nifti files, the rp*.txt files (realignment), the art_regression_outliers_auf*mat (scrubbing) and the art_regression_timeseries_auf*mat (QA). The resulting files have 100 volumes/rows each. I have then entered the cut files to a new CONN project via GUI. 

I'd be very grateful for your help.

I'm getting the following error message:
