Do I have to modifiy the array sizes somewhere in the source files?

I have compiled flex_extract v7.1.3, following the instruction described in .

I realized that an east-west width (RIGHT - LEFT) and a north-south width (UPPER - LOWER) in the CONTROL file must be divisible by a grid spacing (GRID) to avoid this error.

Please close this ticket. Thank you.
