DESCRIPTION

       SPLASH:  A  visualisation  tool  for  SPH data (c)2004-2017 Daniel Price v2.8.0 [6th April

       Command line options:

       -p fileprefix
              : change prefix to ALL settings files read/written by splash

       -d defaultsfile
              : change name of defaults file read/written by splash

       -l limitsfile
              : change name of limits file read/written by splash

       -e, -ev
              : use default options best suited for line plotting (.ev files)

       -360   : set default options suited to 360 video

       -lm, -lowmem
              : use low memory mode [applies only to sphNG data read at present]

              to  phantom : convert SPH data to binary dump file for PHANTOM to gadget  : convert
              SPH data to default GADGET snapshot file format

              Grid conversion mode ("splash to X dumpfiles"):

       splash to grid
              : interpolate basic SPH data (density, plus velocity if present in data)

              to 2D or 3D grid, write grid data to file (using default output=ascii)

       to gridascii
              : as above, grid data written in ascii format

       to gridascii2
              : grid data written in ascii format, all in one file

       to gridbinary
              : as above, grid data in simple unformatted binary format:

       write(unit) nx,ny,nz,ncolumns,time
              [ 4 bytes each ]

       write(unit) (((rho(i,j,k),i=1,nx),j=1,ny),k=1,nz)
              [ 4 bytes each ]

       write(unit) (((vx(i,j,k), i=1,nx),j=1,ny),k=1,nz)
              [ 4 bytes each ]

       write(unit) (((vy(i,j,k), i=1,nx),j=1,ny),k=1,nz)
              [ 4 bytes each ]

       write(unit) (((...(i,j,k),i=1,nx),j=1,ny),k=1,nz)
              [ 4 bytes each ]

       allto grid
              : as above, interpolating *all* columns to the grid (and output file)

       allto gridascii
              : as above, with ascii output

       allto gridbinary
              : as above, with binary output

              Analysis mode ("splash calc X dumpfiles") on a sequence of dump files:

       splash calc energies
              : calculate KE,PE,total energy vs time

              output to file called 'energy.out'

       calc massaboverho : mass above a series of density thresholds vs time
              output to file called 'massaboverho.out'

              : maximum of each column vs. time

              output to file called 'maxvals.out'

       calc min
              : minimum of each column vs. time

              output to file called 'minvals.out'

       calc diff
              : (max - min) of each column vs. time

              output to file called 'diffvals.out'

       calc amp
              : 0.5*(max - min) of each column vs. time

              output to file called 'ampvals.out'

       calc delta
              : 0.5*(max - min)/mean of each column vs. time

              output to file called 'deltavals.out'

       calc mean
              : mean of each column vs. time

              output to file called 'meanvals.out'

       calc rms
              : (mass weighted) root mean square of each column vs. time

              output to file called 'rmsvals.out'

       calc tracks
              : track particle data vs time for selected* particle,

              output to file called 'tracks.out'

              ( * select "xy limits relative to particle" in l)imits menu", or

              press "t" in interactive mode, and save settings to splash.defaults )

              the above options all produce a small ascii file with one row per input file.   the
              following  option  produces  a  file equivalent in size to one input file (in ascii
              format):

       calc timeaverage
              : time average of *all* entries for every particle

              output to file called 'time_average.out'

       calc ratio
              : ratio of *all* entries in each file compared to first

              output to file called 'ratio.out'
