# Installation of `phq`
cd into Workfall2022
`cd Workfall2022`

git clone `phq` using the command below

`git clone https://github.com/MineralsCloud/phq.git`

Then proceed as follows
`cd phq`
`cd system`

If using gfortran compiler,
`cp makefile_linux_gfortran ../src`

If using ifort,
`cp makefile_linux_ifort`

Go back to `src` directory
`cd ../src`

Rename your makefile (Here we use `makefile_linux_gfortran`)
`mv makefile_linux_gfortran makefile`

Then,
`make`

We now have `phq` installed. Copy it to `examples/Si`
`cp phq ../examples/Si`

Now run the calculation
`cd ../examples/Si/`
`./phq < input`

Once the calculation has run proceed as follows,
`cd postprocessing/dispersion`
`cp ../../dynmatmd* .`
`q2r.x < q2r.in > q2r.out`
`matdyn.x < dispersion.in > dispersion.out`
`plotband.x < plotband.in > plotband.out`
