The hop_input.c file has been  modified to make hop compatible with multi-file
Ramses format. For example, the following command line:

./hop -in ./output_00021/part_00021.out -p 1.

tells hop  to parse files  part_00021.out00001 to part_00021.out0000N  where N
stands for the number of processors used to produce the snaphot. 

Regroup can be run using the following command:

./regroup -root output_hop -douter 80. -dsaddle 200. -dpeak 240. -f77

Positions can be computed using

./poshalo -inp output_00021 -pre zregroup -xmi 0.1 -xma 0.9

Here is a full example on a ramses zoom simulation:

./hop -in output_00347/part_00347.out -p 1. -o hop00347
./regroup -root hop00347 -douter 80. -dsaddle 200. -dpeak 240. -f77 -o grp00347
./poshalo -inp output_00347 -pre grp00347 -xmi 0.375 -xma 0.625 -ymi 0.375 -yma 0.625 -zmi 0.375 -zma 0.625
