Dear all, I am trying to sort an array that consists of files names I got from a directory with readdir(). The names of the files in the directory (in order) are like below. 
9.10.force.0.5.1LGY.pdb
29.30.force.0.5.1LGY.pdb
30.31.force.0.5.1LGY.pdb
31.32.force.0.5.1LGY.pdb
....
....
100.101.force.0.5.1LGY.pdb
101.102.force.0.5.1LGY.pdb
....
....
200.201.force.0.5.1LGY.pdb
201.200.force.0.5.1LGY.pdb

As far as I could figure out, sort() function doesn't sort the way I want it to, since it sorts alphabetically or numerically. It starts with 
100.101.force.0.5.1LGY.pdb
101.102.force.0.5.1LGY.pdb

[download]
and continues in this manner, and then places the file 9.10.force.0.5.1LGY.pdb to its place alphabetical wrt its alphabetical order. However, I want to sort these files with respect to their first digit. If any of you can advice a way to do it, I'd appriciate. Thanks a lot.
