rRNA contextual data (metadata)

for environmental sequences

 

 

 

 

What are contextual data?

 

Contextual data (also called metadata) is a standardizedOpens in a new window/tab structure of data describing aspects like geographic location (longitude, latitude) and habitat characteristics (depth, temperature, etc) from which a sequence was retrieved, how it was processed (vectors and primers), etc. Metadata information needs to be attached to the sample files before submitting them to international databases (NCBI). Metadata is important because it adds additional value to samples submitted to a database.

 

Following the MIGS/MIMS (Minimum Information About a Meta-Genome SequenceOpens in a new window) standards for environmental samples at least the GPS position (longitude, latitude), depth/altitude and time of sampling will become mandatory.

 

 

Automatic metadata integration

 

The SILVA team has started a number of projects to facilitate and improve the integration of metadata. DNA Baser is able to automatically read the metadata template file provided by SILVA ribosomal database projectOpens in a new window/tab and automatically integrate them into contigs during sequence assembly or into existing FASTA files.
