An R package (compatible with SCope) to create generic .loom files and extend them with other data e.g.: SCENIC regulons, Seurat clusters and markers, ... The package can also be used to read data from .loom files.

• HDF5 >= 1.10.1

For Linux and MacOS machines, version 1.10.1 can be installed with this snippet:

curl -O https://support.hdfgroup.org/ftp/HDF5/releases/hdf5-1.10/hdf5-1.10.1/src/hdf5-1.10.1.tar
cd hdf5-1.10.1
./configure
make -j4
make check
make install

To install HDF5 on a Windows machine, please use the prebuilt binaries available at https://www.hdfgroup.org/downloads/hdf5/.

For other HDF5 releases, please visit https://support.hdfgroup.org/ftp/HDF5/releases/.

Installation should take less than one minute.
