Using reference genomes with refgenie
Reference genomes used in genomics pipelines can be accessed via refgenie.
Please refer to DANGPU user guide for more details.
In short, you can find available reference genomes like this:
module load dangpu_libs python/3.7.13 refgenie/0.12.1
refgenie list
which will output a list of available genomes.

You can further find contents of each reference genome using list -g option:
refgenie list -g GRCh38
which gives you the information on available assets for the reference genome of interest:

finally, you can find a path to a specific asset as <genome>/<asset>:<tag>
refgenie seek GRCh38/blacklist:CUTANDRUN
which gives you a path to the asset file:

Reference genome options for human
For human reference genome there are several options:
GRCh38 - the most updated reference genome that we suggest for new projects starting from 2024 and on. We currently use this as our default reference genome for human.
GRCh38_legacy - The human reference genome the Genomics Platform used 2017-2023.
GRCh38_dm6 - hybrid genome between GRCh38_ensembl and dm6_ensembl. This can be used for alignments when you have used spike-in from the fly. This reference contains only fasta and bowtie2 index.
GRCh38_refgenie (same as GRCh38) - the reference genome pulled from refgenie. Genomics Platform does not use this reference but it is available for users. Please note that if you run nf-core pipelines and use GRCh38 as reference genome, it will use GRCh38 from AWS_iGenomes reference genome instead of refgenie local list.
Reference genome options for mouse
For mouse reference genome there are also several options:
GRCm39 - the newest reference genome that we recommend for new projects starting from 2024 and on. This genome is the default reference genome for running Genomics Platform pipelines.
mm10_legacy - This is the mouse reference genome we used 2017-2023.
GRCm39_dm6 - hybrid genome between GRCm39_ensembl and dm6_ensembl. This can be used for alignments when you have used spike-in from the fly.
Other reference genomes
There are various spike-in genomes included in refgenie:
dm6_ensembl
dm6_FlyBase
puc19
lambda
Spombe_h90

Characteristics
This genome genome uses fasta (GRCh38.p14 primary assembly from soft-masked genome) and ensembl_gtf (Ensembl release 111) to generate star_index (using STAR 2.7.11b) bowtie2_index (using bowtie2 v.2.5.3) bismark_bt2_index (using bismark v.0.24.2).

blacklist files contain regions prone to misalignment or bias in genomic analysis.
blacklist:ENCODE is sourced from ENCODE project for use with ATAC/ChIP-seq and

10x indexes
Default Cellranger index 10x_index for for gene expression is gex-2024-A which is a local copy of the precompiled Cellranger genome version 2024-A. However, for 100% compatibility with bulk genomes you can also use the tag 7.2.0 which has used refgenie local assets to compile a custom cellranger reference using cellranger version 7.2.0:
refgenie seek GRCh38/10x_index:7.2.0
