 The write benchmark can be passed the -c parameter to enable output compression. Both benchmarks take an optional -a parameter to request that homogeneous aggregates (i.e. "float4") be used instead of using separate arrays for each position/velocity component.

+The repository includes a genericio Python module that can read genericio-formatted files and return numpy arrays. This is included in the standard build. To use it, once you've built genericio, you can read genericio data as follows:
+
+{{{
+$ export PYTHONPATH=${GENERICIO_DIR}/python
+$ python
+>>> import genericio
+>>> genericio.gio_inspect('m000-99.fofproperties')
+Number of Elements: 1691
+[data type] Variable name

+[i 32] fof_halo_count
+[i 64] fof_halo_tag
+[f 32] fof_halo_mass
+[f 32] fof_halo_mean_x
+[f 32] fof_halo_mean_y
+[f 32] fof_halo_mean_z
+[f 32] fof_halo_mean_vx
+[f 32] fof_halo_mean_vy
+[f 32] fof_halo_mean_vz
+[f 32] fof_halo_vel_disp

+(i=integer,f=floating point, number bits size)
