[BiO BB] program for sequence length

[Karger, Amir]

Check out the Scriptome (yes, this is an advertisement.) at http://sysbio.harvard.edu/csb/resources/computational/scriptome/ , which is a set of Perl one-liners you cut and paste onto your command line to do bio-y text-y thigns.

Use the change_fasta_to_tab tool to change your fasta to a tab-delimited file with ID, description, sequence. Then use the calc_col_length tool on the result, which will add another column giving the length of the sequence column. You can throw that into excel and hide the sequence column (or use choose_cols_to_delete to make a file without the seqeuences themselves) and then read through it at your leisure.

Feel free to contact me offline for details.
