Hey, I've got a question about using a reference to an array in a while loop. My folders with the data from different subjects are named abc_001, abc_002, abc_003 and so on. Now I want to tell my script to go in each subfolder and do some processing steps for alle the subjects. 

$i=1;
while ($i<=4);
{chdir ($i) or die "Konnte Verzeichnis $i nicht öffnen";
foreach ("T1_Map","T2_Map", "PD_Map", "T2STAR_Map")
{ 
system ("fslreorient2std $_.nii.gz $_._swapped.nii.gz")
system ("bet $_._swapped.nii.gz $_._swappedbrain.nii.gz -m");
}
chdir ("..");
}
continue
{
$i ++;
}

When I name the folder with "1", "2" etc. there is no problem, but I would prefer naming them abc_001, abc_002 etc. Is there a option I define my subjects using an array and referencing them in the while loop, so the while loop uses the subjects from the array? Thanks a lot!
