Currently a new bin is defined when its predecessor in the searching (either sequential or sorted) has a different mass. In some future version perhaps a fuzzyness or histogramming option will be offered.
The output is suitable to be parsed by awk(1) or tabmath(1NEMO) and can be used in snapmask(1NEMO) to select certain particles by mass. snapcopy can perhaps also be of some use.
The glnemo2(1NEMO) program uses a select= keyword by which different mass groups can be given a different color.
0 0:8191 = 8192 Mass= 3.4332e-06 TotMas= 0.0281248 CumMas= 0.0281248 1 8192:12287 = 4096 Mass= 1.5259e-05 TotMas= 0.0625009 CumMas= 0.0906256 2 12288:28671 = 16384 Mass= 9.7275e-06 TotMas= .159375 CumMas= .250001 3 28672:45055 = 16384 Mass= 6.1035e-05 TotMas= .999997 CumMas= 1.25 4 45056:49151 = 4096 Mass= 0.00015259 TotMas= .625009 CumMas= 1.87501For sort=f it will also also report the optimal select= string for glnemo2(1NEMO) , for example:
# Found 6 species: select=0:7999,8000:11999,12000:17999,18000:25999,26000:29999,30000:35999 # example to view all particle species by a different color glnemo2 snap.out $(snapmstat snap.out | grep select=)
