DatABEL (version 0.9-6)

File-Based Access to Large Matrices Stored on HDD in Binary Format

Description

Provides an interface to the C++ FILEVECTOR library facilitating analysis using large (giga- to tera-bytes) matrices. Matrix storage is organized in a way that either columns or rows are quickly accessible. DatABEL is primarily aimed to support genome-wide association analyses e.g. using GenABEL, MixABEL and ProbABEL.
