MAGMA is a tool for gene analysis and generalized gene-set analysis of GWAS data. It can be used to analyse both raw genotype data as well as summary SNP p-values from a previous GWAS or meta-analysis.
The manual can be downloaded here.
The primary publication for MAGMA is:
de Leeuw C, Mooij J, Heskes T, Posthuma D: MAGMA: Generalized gene-set analysis of GWAS data. PLoS Comput Biol 11(4): e1004219. doi:10.1371/journal.pcbi.1004219 (link)
When using MAGMA, please refer to this paper.

Program and auxiliary files
Download links for the program itself as well as a number of auxiliary files can be found below. For Linux, binaries were compiled on Debian but will also usually run on other distributions. Additional statically linked binaries are provided for both Linux and Windows. In case certain libraries cannot be found due to some difference in operating system versions (typically an error message regarding a missing .so or .dll file), using these may resolve the problem.
The MAGMA source code can also be downloaded below, which can be used to compile the program on the target system if this is not supported by the provided binaries (note that standard copyright still applies; the MAGMA binaries and source code may not be distributed or modified).
A log of all the major changes in the latest version can be found here.

For the gene location files, gene locations for protein-coding genes were obtained from the NCBI site. Locations are defined as the region from transcription start site to transcription stop site. These location files contain Entrez gene IDs.
The SNP synonym file contains lists of synonymous SNP rs IDs that refer to the same SNP, up to date to dbSNP release 147. These synonyms can be included in MAGMA analyses to improve mapping of SNPs across different files, in particular SNP p-value files and reference data. The 1,000 Genomes reference data files below already include a data-specific synonym file.

The reference data files are created from Phase 3 of 1,000 Genomes. The SNP locations in the data are in reference to human genome Build 37. An additional file with definitions of the sub-populations is available as well, which can be used to extract specific sub-populations from the 1,000 Genomes data files. Data-specific SNP synonym files are included with the data.
