I was running the above resting-state proc script and got an error message below.



Warping used up maximum iterations
even after doubling number of iterations to 274.
Convergence might not have been reached.

If you find the alignment poor, try
rerunning the script with a transform
type of fewer parameters (-xform) or by using
an even higher number of iterations (-maxite).
You can also choose to continue with the
current result (dset: __ats_tmp__reg_warpdriveout+orig
by using the option: -OK_maxite

Script will stop ...

#**ERROR Failed in affine step
** ERROR - script failed
3dbucket: No match.



I wasn't sure what is the issue here. Is it simply be solved by adding -OK_maxite to the script?


Thank you in advance for your help,
Jun
