[maker-devel] fasta_merge problem

[Carson Holt]

The main function of fasta_merge is to use the datastore index file to find and concatenate fasta files spread throughout the datastore.  If you wish to merge a handful of fasta files into one because you made 10 chunks, you can simply merge the files you want using the Linux ‘cat’ command.

Example 1: ‘cat file1 file2 file3 file4 > merge.fasta'

Example 2: ‘cat *output/*.maker.proteins.fasta > merge.maker.proteins.fasta'

After that, I used gff3_merge and fasta_merge to produce output for each of the chunks. Then I tried using these same tools for merging the different outputs into one, and while gff3_merge ran as expected, fasta_merge did not. I used the following command:
