Hello, 

I have 1300 NIFTI files, then I am trying to perform an AC-PC alignment using the next command in a loop.

acpcdetect -center-AC -i "PATH-TO-NII"

The sh script is attached.

I am getting this random errors in different files. I have executed the sh several times and this problem is not always in the same files. Then, when I run acpcdetect in the nii file with error, it works properly.

acpcdetect(5448,0x7fffa18f3380) malloc: *** error for object 0x7fbff3500308: incorrect checksum for freed object - object was probably modified after being freed.

*** set a breakpoint in malloc_error_break to debug



acpcdetect(4333,0x7fffa18f3380) malloc: *** error for object 0x7fb0e85002f8: incorrect checksum for freed object - object was probably modified after being freed.

*** set a breakpoint in malloc_error_break to debug

Hi Arvid,

There seems to be a problem with your script.  Have you tried running just a single case by itself without the use of the script?
