Here post your question
while trying to execute " perl inflategro.pl system_inflated_em.gro 0.95 DPPC 0 system_shrink1.gro 5 area_shrink1.dat " at the step three of membrane protein tutorial I get the following error.
"Use of uninitialized value $box_x in multiplication (*) at inflategro.pl line 259.
Use of uninitialized value $box_y in multiplication (*) at inflategro.pl line 260.
Scaling lipids…
There are 0 lipids…
Illegal division by zero at inflategro.pl line 300."
I took a look at inflategro.pl file and the line 259,260 and 300 look like this.
" 259 $box_x=$box_x$scale;*
** 260 $box_y=$box_y*$scale;**
300 $atomperlipid= $zaehler/$pcount; "
What can do to fix these errors? Could there be some errors in my input files?
Thank you!
