File http://rmaps.cecsresearch.org/STAR/STARindex.tgz referenced in rMATS is no longer available. So to be able to test fast examples we need to generate an index of the reference genome ourselfs http://people.duke.edu/~ccc14/duke-hts-2018/bioinformatics/genome_prep.html .

Use bellow to install STAR software :

@anthill23:~$

srun -J star_compile --pty bash -l

cd ~/anthill23_rmats/
wget https://github.com/alexdobin/STAR/archive/2.7.1a.tar.gz
tar xzf 2.7.1a.tar.gz
cd STAR-2.7.1a
cd source
make STAR

exit

Use bellow to generate index required to run sbatch example: fastq (more info how to use STAR ) .

@anthill23:~$

srun -J create_index -N1 -n16 --mem 220G --pty bash -l

cd ~/anthill23_rmats/gtf
wget ftp://ftp.ensembl.org/pub/release-91/gtf/homo_sapiens/Homo_sapiens.GRCh38.91.gtf.gz
gunzip Homo_sapiens.GRCh38.91.gtf.gz
wget ftp://ftp.ensembl.org/pub/release-91/fasta/homo_sapiens/dna/Homo_sapiens.GRCh38.dna.toplevel.fa.gz
gunzip Homo_sapiens.GRCh38.dna.toplevel.fa.gz
