Here is a changelog for the 2.2.0 version:

New features

  • Five new species have been added:

- European amphioxus, `Branchiostoma lanceolatun` (assembly Bl71nemr; species key: `Bla`): http://vastdb.crg.eu/libs/vastdb.bla.01.12.18.tar.gz

- Centipede, `Strigamia maritima` (assembly Smar1; species key: `Sma`): http://vastdb.crg.eu/libs/vastdb.sma.01.12.18.tar.gz

- Fruit fly, `Drosophila melanogaster` (assembly BDGP6; species key: `Dme`): http://vastdb.crg.eu/libs/vastdb.dme.01.12.18.tar.gz

- Worm, `Caenorhabditis elegans` (assembly WBcel235; species key `Cel`): http://vastdb.crg.eu/libs/vastdb.cel.01.12.18.tar.gz

- Sea anemone, `Nematostella vectensis` (assembly GCA_000209225; species key `Nve`): http://vastdb.crg.eu/libs/vastdb.nve.01.12.18.tar.gz


Further information about the assemblies and species can be found in the source publication: Torres-Méndez, A., Bonnal, S., Marquez, Y., Roth, J., Iglesias, M., Permanyer, J., Almudí, I., O’Hanlon, D., Guitart, T., Soller, M., Gingras, A.-C., Gebauer, F., Rentzsch, F., Blencowe, B.J.B., Valcárcel, J., Irimia, M. (2019). A novel protein domain in an ancestral splicing factor drove the evolution of neural microexons. Nature Ecol Evol, 3:691-701.


  • `tidy` allows filtering events by coverage using a groups config file. Using this option, the minimum number or fraction of samples with coverage (`--min_N` or `--min_Fr`) applies to EACH group of samples.
  • `combine` allows to create tables of normalized cRPKMs using `normalizebetweenarrays` from the `limma` R package.
  • `compare_expr` provides a list of ranked genes sorted by fold change to be used directly in GSEA (with rnk.txt extension).
  • `compare` provides the list of all AS events with coverage, when the option `--GO` is provided.


Updates and fixes

  • Quality control to make sure the expression files have the same number of genes when combining.
  • Improvements in README and help messages.
  • Various other minor fixes and improvements.
