Accessing the Data

The MVL files can be accessed either using C-level libMVL library, or using R package RMVL.

Plot and Examples

The plot at the top of the page was produced using view_summary.R script included in the examples. We also provide examples that allow to explore atlas programmatically, see README for more details.

If you are new to R, here is a brief introduction to R.

Optimized for Solid State Drives

The Mapped Vector Library (MVL) format is optimized for use with solid state drives (SSDs), which allow random access to the data.
