Apart from the changelog, this is a more informal section where I will inform about new features that have been (or will be) implemented in Scaden.
Scaden v1.1.0 - Performance Improvements and
scaden merge tool (21.03.2021)
Scaden v1.1.0 brings significantly improved memory consumption for the data simulation step, which was a frequently asked for feature.
Now, instead of using about 4 GB of memory to simulate a small dataset, Scaden only uses 1 GB. Memory usage does not increase
with the number of datasets anymore. This will allow to create datasets from large collections of scRNA-seq datasets without
needing excessive memory. Furthermore, Scaden now stores the simulated data in
.h5ad format with the full list of genes.
This way you can simulate from a scRNA-seq dataset once and combine it with other datasets in the future. To help with this,
I've added the
scaden merge command, which takes a list of datasets or a directory with
.h5ad datasets and creates
a new training dataset from it.
