RefSeq Rollback
A collection of scripts to create historical RefSeq versions.
Downloading the necessary files
The two files you'll need to rollback to a desired RefSeq version are:
- The current bacterial RefSeq FASTA file
- The catalog file associated with the version you want to rollback to.
Two scripts are provided to help you download these files:
./download_latest_bacterial_refseq.sh
./download_refseq_catalog.sh 80
download_latest_bacterial_refseq.sh will create a directory and download the latest bacterial RefSeq FASTA files, concatenate them and delete the pieces. download_refseq_catalog.sh will download the catalog file you want to rollback to, in the example we chose 80, though any version can be selected.
Rolling back to a desired RefSeq version
If you want to use these files to roll back to version 80, you would do the following:
./refseq_rollback.pl -catalog RefSeq-release80.catalog.gz \
-fasta RefSeq-release88.fasta.gz \
-out RefSeq-release80.fasta
Diversity calculations
In the MetaDB manuscript we present diversity metrics for bacterial RefSeq over time. The script used to create the OTU table in the analysis is create_otu_table.pl.
