Hi Chetna,

From [http://manual.gromacs.org/documentation/current/install-guide/index.html:](http://manual.gromacs.org/documentation/current/install-guide/index.html:)

Alternatively, you can download and unpack the GROMACS regression test suite [http://gerrit.gromacs.org/download/regressiontests-2020.3.tar.gz](http://gerrit.gromacs.org/download/regressiontests-2020.3.tar.gz) tarball yourself and use the advanced `cmake` option `REGRESSIONTEST_PATH` to specify the path to the unpacked tarball, which will then be used for testing

Give that a try.

Dan
