I am running 3dDespike on AFNI version 16.2.16. For testing purposes, I am running my analysis on the same dataset on two OS (CentOS 6.5 and CentOS 7.2). Comparing the outputs from the two OS, I’ve noticed that there are differences in the values. Meanwhile, the input files for each subject on both OS are identical. The differences are minor, however they pose some concerns for subsequent analyses.
I was wondering if anyone can advise on what might contribute to these differences in the 3dDespike outputs?
Many thanks.
