READASCII(1) TIPSY COMMANDS READASCII(1)
readascii - read an ascii file
readascii is a command to read in the currently open ascii
file and write it out in binary form into file filename.
The ascii2binary program also converts TIPSY ascii format
into TIPSY binary format. The oldreadascii command is
used for ascii files with the old 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. After the binary file is written
the ascii file is closed and the binary file filename is
opened. Binary files can be opened or closed using the
openbinary and closebinary commands.
The ascii file should be of the TIPSY ascii form and typi-
cally contains all the time frames in sequential order.
Each time frame should be of the form:
ntotal, 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
grav_softening_length_dark_particles(i), i = 1 to
grav_softening_length_star_particles(i), i = 1 to
density(i), i = 1 to ngas
temperature(i), i = 1 to ngas
sph_smoothing_length(i), i = 1 to ngas,
metals_gas(i), i = 1 to ngas,
metals_star(i), i = 1 to nstar,
formation_time(i), i = 1 to nstar,
potential_energy(i), i = 1 to ntotal,
where ntotal is the total number of particles, ngas is the
number of gas particles, ndark is the number of dark mat-
ter 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. Therefore, each
time frame should contain 9*ntotal+3*ngas+2nstar +3 lines.
After the binary file is made a specific time must still
be loaded using the loadbinary command.
