Name

snapmody - convert snapshot to Mody’s pos-vel files

Synopsis

modysnap [parameter=value]

Description

snapmody converts snapshot-style datasets from the n-mody MOND N-body integrator to a standard NEMO snapshot(5NEMO) .

It is also automatically called by runmond(1NEMO) to convert the input conditions, from snapshot(5NEMO) format, into the format that the rmond program understands.

Note: this program is forced to convert to single precision, even if the input dataset is in double precision.

Output files from QuMond are the same as MODY files, except they don’t carry a header.

Parameters

The following parameters are recognized in any order if the keyword is also given:
in=
Input snapshot file. No default. No default.
out=
Output mody pos-vel file (moutXX.bin style).
out2=
If given, this NEMO history of the input dataset is written here. Default: none
swap=t|f
Swap bytes in each int/float if endianism differs . Not implemented yet.
header=t|f
Write a header? Needed for MODY style, but e.g. QuMOND only carries particle information. Default: true

Caveat

Will only process the first snapshot.
