 ## Configure pipeline
 
-Go in the snakemake directory
+### Download annotation files
+
+Go in the snakemake directory and create a new annotation directory
 ```
 cd riboseq_pipeline/snakemake
+mkdir annotation
+```
+
+Download an annotation file (e.g. gtf from ENSEMBL) and uncompress it
+```
+wget ftp://ftp.ensembl.org/pub/release-90/gtf/homo_sapiens/Homo_sapiens.GRCh38.90.chr.gtf.gz
+gunzip Homo_sapiens.GRCh38.90.chr.gtf.gz
+```
+
+Download a chromosome sequences file (e.g. soft-masked fasta from ENSEMBL) and uncompress it
+```
+wget ftp://ftp.ensembl.org/pub/release-90/fasta/homo_sapiens/dna/Homo_sapiens.GRCh38.dna_sm.primary_assembly.fa.gz
+gunzip Homo_sapiens.GRCh38.dna_sm.primary_assembly.fa.gz
+```
+
+Then download rRNAs (e.g. from RefSeq). For the members of the group you can use the following file:
+```
+cp /scicore/home/zavolan/gypas/projects/resources/human/rRNA/rRNA_joao.fa
 ```
 
+Finally copy or create a file with oligos. For the members of the group you can use the following file:
 ```
+cp /scicore/home/zavolan/gypas/projects/resources/human/rRNA/oligos.txt
+```
