Is acc2tax database required in v1.2.4?

[modolon]

The short_seqs/classify commands in Eukfinder v1.2.4 include a parameter for an acc2tax database path (--acc2tax /path/to/Acc2Tax_DB), but this dependency is missing from the "Building Custom Databases" documentation.

Questions:

1. Is the acc2tax database mandatory for Stage 2 (PLAST-based) classification?
2. If so, could you provide the specific requirements or a script to generate this database so it is compatible with custom Centrifuge/PLAST indices?

No, the new version doesn't need acc2tax database
