CCL: help needed

 Sent to CCL by: "Richard L. Wood" [rwoodphd##msn.com]
 Hi all,
 This question isn't a direct computational chemistry question, but an indirect
 one.  So please bear with me.
 I'm trying to analyze the output of a 1 nanosecond MD calculation that I ran
 using the program NAMD.  Since it's a text file, I could use MS Excel to open it
 and sort the energies from lowest to highest value, which is what I would like
 to do.  However, MS Excel has a limit of about 65000 lines of text (or rows)
 that a file can contain.  Mine has 2000000 lines of text, so that my file is too
 big.  My workaround is to open the file in MS Word, and cut it into pieces that
 can be opened in MS Excel.  Then I can find the minimum energy fro each piece,
 save that value, and then when done, find the overall minimum.  Once I've done
 this, I can find the corresponding frame number in the file that contained it,
 go to the trajectory and save those coordinates.
 However, as you can imagine, this isn't a very efficient process.  My simulation
 takes about 2 and half hours or so to run, while this analysis takes about two
 hours to do.  I can therefore do about one of these in a day, as I have another
 non-computational "job" that I am doing.  At some point, I will be
 running some smalled calculations, which will take much less than two hours to
 run, and so the analysis will take longer than the simulation!
 My question is this:  does anyone know of a spreadsheat program where I can a)
 import a text file of more than 65000 rows easily, b) can sort a given column of
 that file, and c) works under Windows and is free?  I've tried Quattro Pro, and
 all the file comes out in a single row!
 TIA,
 Richard
