OLDREADASCII(1)           TIPSY COMMANDS          OLDREADASCII(1)




NAME

       oldreadascii - read an old format ascii file


SYNOPSIS

       oldreadascii filename type


DESCRIPTION

       oldreadascii  is  a  command to read in the currently open
       ascii file if it is in the old ascii format and  write  it
       out  in binary form into file filename.  This command only
       exists to preserve backwards compatibility.  The readascii
       command is used for ascii files with the usual format.  If
       no ascii file is open or if a binary file is already  open
       an  error  is generated.  Ascii files are opened using the
       openascii command and binary files are  closed  using  the
       closebinary command.  After the binary file is written the
       ascii file is closed and  the  binary  file  file-name  is
       opened.   After  the  binary  file is made a specific time
       must still be loaded using the loadbinary  command  before
       any plotting can be done.

       The ascii file should be of the old ascii form and contain
       all the time frames in sequential order.  If type  is  sph
       each time frame should be of the form:


              ntotal, ndimensions, time, ngas, nstar

              mass(i), i = 1 to ntotal

              x_position(i), i = 1 to ntotal

              y_position(i), i = 1 to ntotal

              z_position(i), i = 1 to ntotal

              x_velocity(i), i = 1 to ntotal

              y_velocity(i), i = 1 to ntotal

              z_velocity(i), i = 1 to ntotal

              density(i), i = 1 to ngas

              temperature(i), i = 1 to ngas

              sph_smoothing_length(i), i = 1 to ngas,
       where ntotal is the total number of particles, ngas is the
       number of gas particles, and nstar is the number  of  star
       particles.   The  first  ngas  particles should be the gas
       particles and the last nstar particles should be the  star
       particles with the dark particles being in the middle.  If
       type is nosph each time frame should be of the form:


              ntotal, ndimensions, time

              mass(i), i = 1 to ntotal

              x_position(i), i = 1 to ntotal

              y_position(i), i = 1 to ntotal

              z_position(i), i = 1 to ntotal

              x_velocity(i), i = 1 to ntotal

              y_velocity(i), i = 1 to ntotal

              z_velocity(i), i = 1 to ntotal.
