Good morning, I’m having troubles with 3dcalc. The line is
3dcalc -a ‘mask_x+orig[0]’ -b map_x+orig -expr ‘b+step(a)(a(32+1)-b)’ -prefix map_x_1
AFNI version is AFNI_18.3.03 (Oct 19 2018) [64-bit]. This line is inside a for loop, and it has been executed 30 times before giving the error. map_x is created by another 3dcalc line, and it is a 3D dataset, while mask_x is 3D+time, with 210 time points. The message I receive is
Fatal Signal 11 (SIGSEGV) received
3dcalc main

I tried to rerun the program and it always fail at the same iteration. If I try to run 3dinfo mask_x+orig or 3dinfo map_x+orig I get the warning “*+ WARNING: THD_zzprintf() long string truncation = the ZSS syndrome” an infinite number of times. But I can open both datasets with the afni display gui, and they look correct.
