The TRACK INFO command gives a summary of what is contained in the track file:
Some messages are written as Sabrina attempts to open the file and figure out its type.
Successfully read nps = -1 in ASCII mode
Will try to read as ascii file
New (>= MCNP 4A) format found
The first integer in the file is used as a version flag. This number is > 0 in an older version of the particle track file format. The INFO report first tells the name of the file
Particle Track File ptracall.trk
followed by an identification field, in this case the MCNP title line
ID : MCNP input deck for ptrack test
and then the name, version, and load date of the program that wrote it
Origin: mcnp . 4a . 10/01/93
and the date and time on which the track file was written
Date : 12/15/93 15:31:09
Several quantities are written to the track file when various types of events occur. Which quantities are written varies with both the event type and the options chosen when creating the file. A list of what is available is given:
Per-History Information :
NPS NEXT
Per SOURC Event Info. :
NEXT NODE ISRCE CELL MAT NCOLL
X Y Z COSX COSY COSZ ENRGY WGT TIME
followed by similar lines for bank, surface crossing, collision, and termination events.
A summary of the extent of the tracks for each particle type (neutron, photon, electron) follows:
