Map2NCBI-package: Mapping Markers to the Nearest Genomic Feature

In Map2NCBI: Mapping Markers to the Nearest Genomic Feature

Mapping Markers to the Nearest Genomic Feature

Description

Allows the user to generate a list of features (gene, pseudo, RNA, CDS, and/or UTR) directly from NCBI database for any species with a build available. Option to save downloaded and formatted files is available, and the user can prioritize the feature list based on type and assembly builds present in the build used. The GetGeneList function can now handle query of the NCBI for genome builds released prior to 2018 as well as the latest build for that species. The user can then use the list of features generated or provide a list to map a set of markers (designed for SNP markers with a single base pair position available) to the closest feature based on the map build. This function does require map positions of the markers to be provided and the positions should be based on the build being queried through NCBI.
