     3Starting with rXXX (resp. GiBUU 2019, patch XXX), some additional output is possible, were all interactions at a given time step are reported in order to enable a 'replay' of the whole interactions like in a 'movie'.

     5This feature may be switched on by selecting in the input job card

     15Then, two files will be generated:

     17=== File 1: 'collisionList0.txt' ===
     18
     19In this file, all particles after the initialization are listed. For elementary interactions on a nucleus, this includes the nucleons, i.e. the ("real") particles, as also the final state particles of the first interaction, the "perturbative" particles.

     21The format is :

     50In this file, all interactions are listed.

     52The first line indicates the time 'time', the kind of process 'iProc', the number of outgoing particles 'nOut', and the internal coordinates (iEns, iID) of the incoming particles
     53{{{
     54  time, iProc, nOut, iEns1,iID1 [, iEns2,iID2 [, iEns3,iID3 ]]

     56The coding of 'iProc' is:
     57* 1-body:    11= real particle decay, 12= pert.particle decay
     58* 2-body:   211= real+real ,         212= real+pert
     59* 3-body:  3111= real+real+real,    3112= real+real+pert
     60
     61Then 'nOut' lines indicating the outgoing particles are given as in 'collisionList0.txt'.

     77Due to technical reasons, it is not sufficient to just look at the uniqueID of real particles, since this may be repeated in every ensemble. Thus only the combination of ensemble number and unique ID identifies the particle. This is not necessary for perturbative particles. To avoid confusion, here the number of the ensemble is always set to 0.
