I have 100 amino acid residues which have phi and psi angle.These range from -180 to 180 degress. I represented the frequencies of 100 residues in the form of a two dimentional array with the help of references. I took a range of 10 degrees like -180 t0 -170(total i have 36 for phi and 36 for...

each time the value of $line32 is replaced by the value of $line.As soon as the $i==31 (its $i==31 instead of $i==32)we are coming out of inner foreach loop and before that $line32 is assigned the value of $line and we are pushing the value in to the array @userii.. the outer foreach loop...

i guess the following code will work foreach $file(@userff) { open(FILEHANDLE,$file) || die &quot;cann't open the $file!&quot;; @filearray=<FILEHANDLE>; close(FILEHANDLE); $i=0; $line32; LINE: foreach $line(@filearray) { $line32=$line; #here $line32 takes each time a new line $i++; last LINE...
