IMP-specific prokka conda recipe needed
prokka comes by default with
While this makes sense when using prokka for isolate genomes, the use of this step for metagenomes is less apparent.
In particular, this step is very time-consuming, i.e., can take 10 hours or more.
Moreover, the output is currently not used at all by the IMP pipeline.
Hence, creating a dedicated recipe for prokka is suggested. A dedicated recipe would allow us to apply a patch to prokka's perl script to disable the tbl2asn step. While it could also be described in the installation instructions of IMP to comment-out the respective line when using the prokka bioconda recipe, having a dedicated recipe seems to be the cleaner solution.
