in reply to Defining directory/Datas the perl script should work with

"I think there a lot of syntax errors ...

Welcome. Your running with strict, warnings and diagnostics, perl will tell you about problems.

my $dir = "usr/bin/Test_Protokoll"

Should be:

my $dir = "usr/bin/Test_Protokoll";

If this is the same bet you're talking about, you need to specify the output path/file, bet input.file outdir/out.file -m. You'll also have seen:

"Numeric variables with more than one digit may not start with '0' at bet.pl line 9 (#1)"

So don't do that. You improperly create @filter and then never use it. Consider:

#!/usr/bin/perl use strict; use warnings; use diagnostics; my $dir = 'usr/bin/Test_Protokoll'; my @filters = ('001', '002', '003'); foreach my $filter ( @filters ){ print "filter: $filter\n"; system("bet SYNT_MPRAGE_T1_PD_B0corr YNT_MPRAGE_T1_PD_B0corr_brain + -m"); }

You don't say what you want to do with these filters, and perhaps you want to include $dir as the output path to your bet call. See also $?

    "...should be..." Where is usr/bin/?

    «The Crux of the Biscuit is the Apostrophe»

      Does the OP mean my $dir = "/usr/bin/Test_Protokoll";? The change is a slash before usr.

        Probably something was wrong with his bloody shell today.

    Thanks for your reply! I want to use the filters later on. I want to do a lot of processing steps to for example 30 datasets, so I want to tell the script in each processing step to do it for all the @filters defined datasets, but at the moment i'm not that far. -M
