The SRA Toolkit and SDK from NCBI is a collection of tools and libraries for using data in the INSDC Sequence Read Archives.

February 10, 2022

NCBI's SRA changed the source build system to use CMake in toolkit release 3.0.0. This change is an important step to improve developers' productivity as it provides unified cross platform access to support multiple build systems. This change affects developers building NCBI SRA tools from source. Old makefiles and build systems are longer be supported.

This change also includes the structure of GitHub repositories, which underwent consolidation to provide an easier environment for building tools and libraries (NGS libs and dependencies are consolidated). Consolidation of NGS libraries and dependencies provides better usage scope isolation and makes building more straightforward.

1. ncbi/ngs

   This repository is frozen. All future development will take place in GitHub repository ncbi/sra-tools, under subdirectory ngs/.

2. ncbi/ncbi-vdb (This repository)

   This project's build system is based on CMake. The libraries providing access to SRA data in VDB format via the NGS API have moved to GitHub repository ncbi/sra-tools.

   Old (base URL: https://github.com/ncbi/ncbi-vdb)	New (base URL: https://github.com/ncbi/sra-tools)
   libs/ngs	ngs/ncbi/ngs
   libs/ngs-c++	ngs/ncbi/ngs-c++
   libs/ngs-jni	ngs/ncbi/ngs-jni
   libs/ngs-py	ngs/ncbi/ngs-py
   libs/vdb-sqlite	libs/vdb-sqlite
   test/ngs-java	test/ngs-java
   test/ngs-python	test/ngs-python

3. ncbi/sra-tools

   This project's build system is based on CMake. The project acquired some new components, as listed in the table above.

Windows Defender and a few other anti-virus tools have recently been falsely warning about test-sra.exe.

We suggest verifying MD5 checksums after downloading.
