Daa2info doesn't work (at least) since 6.8.15

I recently upgraded MEGAN to 6.8.18 to get the new hierarchical export that I asked for earlier (thank you for implementing that!). However, my exports does not work any more. I have tried with 6.8.15, 17 and 18 and none of them works; 6.8.12 does work however but doesn’t recognize the --paths option (ids are output).

This is the command and the output I get:

$ /usr/local/megan/tools/daa2info --in AA9340.erne-filter.standards.erne-filter.moranrna.pear.out.unassembled.concat.refseq_protein.daa -r2c SEED --names

(In 6.8.12 there was a message about loading a file, then it got started with the export.)

I also tried with other export categories, besides SEED.

I tried rerunning diamond (0.8.24) as well as the meganizing if this was a file format issue, but to no avail.

You need to specify

-l or --list

This isn’t very intuitive and I will remove this condition in the next release.

Not very intuitive, I agree ;-).

However, I don’t get the --paths option to work. The program outputs ids instead:

$ /usr/local/megan/tools/daa2info --in AA9340.erne-filter.standards.erne-filter.moranrna.pear.out.unassembled.concat.refseq_protein.daa -r2c SEED --list --paths |head

Hi Daniel, this is not a bug, the option “paths” was not implemented for functional classifications. However, I have now implemented this feature and it will be available in the next release.
