mzAccess is a open source web-service software for remote interactive access to the large collections of mass spectrometry data.

What mzAccess is needed for

If you have a lot of mass spectrometry data and need to access them fast and simple from your scripts and programs, then mzAccess is for you.

And mzAccess is really f-fast when you need to get a chunk of data from, say, couple of thousand raw files.

How to use mzAccess

Download Installer, setup mzAccess to computer (Windows-64 bit) where your data are located. Start use of the data with a function calls from your scripts.

Server software

mzAccess server installation package (for Windows 64-bit) is available at download page. Source codes for mzAccess are available at GitHub.

You can try mzAccess with our test instance of mzAccess server, which is set up and running at Charon CMM server.

Client software

The R 3.x client for mzAccess is available from GitHub.
