PICRUSt2 v2.5.0
-
Fixed important bug where the "norm_taxon_function_contrib" column of the contrib (i.e., stratified) output tables contained wrong values (e.g., #206). This was especially clear from the fact that the values were frequently NA or > 1 (when they should all be proportional). Many thanks to @ragavishn and Vincent Darbot for bringing this to my attention.
-
Added several checks to input sequence abundance table (especially when it is provided as a simple TSV table). This should provide more informative error messages regarding how the table is malformed and how it can be fixed.
-
Added check for whitespace in input FASTA file headers to provide informative message (otherwise this often results in issues with hmmalign / placement workflow that isn't obvious from the errors)
-
Bumped versions of gappa and castor dependencies to latest versions.
-
Added "cython" as a dependency to avoid installation problems (thanks @crusher083!)
