hi,
I am writing a PERL script to execute a number of CCP4 commands (ncsmask,
pdbset, and dm) in succession. I have tried using system call or PIPE
command, neither of which work. The ccp4 scripts generated work
independently on the command line.
we do this in the eds map generation script. first create a little shell
script that runs the ccp4 programs:
------
# generate refmac script file
open (OUTFILE,">refmac.com") || die "$! can't open file refmac.com \n";
select (OUTFILE);
if ($tls_flag ne "") {
print "$tlsextract XYZIN $pdbfile TLSOUT $tlsin > tlsext.log\n\n";
}
------
etc.
and then execute it with the system command (of course, you have to make the
file executable first, or maybe "source" it instead of executing it - could
this have been your problem?):
------
close (OUTFILE);
system ("chmod 744 refmac.com");
system ("./refmac.com");
------
works fine on a plain-vanilla linux box
--dvd
p.s.: a propos an earlier thread, a solution is to use answers.com instead of
wikip... e.g.: http://www.answers.com/molecular%20geometry and
http://www.answers.com/topic/dihedral-angle?cat=technology and
http://www.answers.com/topic/alkane-stereochemistry - this should work in the
land of the great firewall; not sure about other orwellian countries (let me
know off-line if it doesn't)
