please do # The following script does the same as the previous one # except that it will write results in a file # so that you don't have to click 47 times on OK. # besides you can keep track of results, which is convenient. open pdb from "net" "1CRN"; $MYFILE = open file "results" in usrstuff for writing; $X = 0; $NBGROUPS = groupcount of "1crn"; do { $SEL = select in "1crn" pos $X; $PHI = phi($SEL); print on $MYFILE $PHI; } while (++$X < $NBGROUPS); close file $MYFILE; thank you
