Description

Process the output of meta.retrieval by first un-zipping downloaded files and renaming them for more convenient downstream data analysis.

Usage

clean.retrieval(x, gunzip = TRUE)

Arguments

x

a vector containing file paths to the output files generated by meta.retrieval.

gunzip

a logical value indicating whether or not files should only be renamed (gunzip = FALSE) or renamed AND unzipped (gunzip).

Details

The output of meta.retrieval usually contains compressed sequence files and a naming convention based on the database the respective file was retrieved from (e.g. Saccharomyces_cerevisiae_cds_from_genomic_refseq.fna.gz). This function helps to format the meta.retrieval output files by

• 1) Automatically uncompress all sequence files in the meta.retrieval output folder

• 2) Automatically rename files from e.g. Saccharomyces_cerevisiae_cds_from_genomic_refseq.fna.gz to Scerevisiae.fa. This allows more convenient downstream analyses and visualizations.

               type = "genome") %>% clean.retrieval()
