Hi AFNI team,
I am wondering the possible reason for a missing field of AFNI version in the output of 3dinfo. For example, I have the output of 3dinfo from one subject like this:
----- HISTORY -----
[lzh@node24.cluster: Thu Sep 27 18:04:07 2018] {AFNI_18.0.09:linux_xorg7_64} 3dDespike -NEW -nomask -prefix r2_despike.nii.gz r1_original.nii.gz
[lzh@node24.cluster: Thu Sep 27 18:04:37 2018] {AFNI_18.0.09:linux_xorg7_64} 3dresample -orient LPI -prefix r3_reorient.nii.gz -inset r2_despike.nii.gz
[lzh@node24.cluster: Thu Sep 27 18:04:59 2018] 3dvolreg -prefix r4_volreg.nii.gz -base 16 -1Dfile ./motion_parameters.1D r3_reorient.nii.gz
See the AFNI version (AFNI_18.0.09:linux_xorg7_64) has been printed out for the first two steps of 3dDespike and 3dresample, but this version information is missing for the last step of 3dvolreg.
However, if I check the same file from a different subject, I got the following:
----- HISTORY -----
[lzh@node6.cluster: Mon Oct 1 09:36:46 2018] {AFNI_18.0.09:linux_xorg7_64} 3dDespike -NEW -nomask -prefix r2_despike.nii.gz r1_original.nii.gz
[lzh@node6.cluster: Mon Oct 1 09:37:04 2018] {AFNI_18.0.09:linux_xorg7_64} 3dresample -orient LPI -prefix r3_reorient.nii.gz -inset r2_despike.nii.gz
[lzh@node6.cluster: Mon Oct 1 09:37:17 2018] {AFNI_18.0.09:linux_xorg7_64} 3dvolreg -prefix r4_volreg.nii.gz -base 63 -1Dfile ./motion_parameters.1D r3_reorient.nii.gz
See the version information are shown for all of the three steps performed in this subject.
I noticed this issue when trying to repeat the "3dvolreg" in the first subject shown above. In that subject, the head motion file (motion_parameters.1D) generated on "Thu Sep 27 18:04:59 2018" is different than what I can currently get with exactly the same command line and input file. I am attaching plots of one movement dimension generated back then in 2018 (the black line) and generated currently (the red line). The two curves look like each other but are not identical. This issue does not exist in the second subject whose 3dinfo shows complete AFNI version. In the second subject, the head motion estimates are identical between now and then.
