       (i)   n_mars_years, n_earth_years -> the number of Mars/Earth years to be simulated in total;
       (ii)  nPCM_ini -> the number of initial PCM runs (at least 2);
-      (iii) nPCM -> the number of PCM runs between each PEM run (usually 2).
+      (iii) nPCM -> the number of PCM runs between each PEM run (usually 2);
+      (iv)  dim -> the dimension of the model (1 for 1D, any other values stand for 3D).
   The script can take an argument:
       - If there is no argument, then the script initiates a PEM simulation from scratch.
       - If the argument is 're', then the script relaunches an existing PEM simulation. It will ask for parameters to know the starting point that you want to. 
+  The script works only with the job scheduler SLURM to submit chained jobs.
 
 # liblaunchPEM.sh:
   Library of bash functions used by the PEM launching script "launchPEM.sh".
 
-# jobPCM.slurm:
-  Bash script file to run the PCM with a SLURM job. The name of the PCM executable file should be adapted. The header corresponds to the ADASTRA supercomputer and should be changed for other machines.
+# PCMrun.job:
+  Bash script file to run the PCM with a SLURM job. The name of the PCM executable file should be adapted. The header corresponds to the ADASTRA supercomputer and should be changed for other machines. In case of 1D, the SBATCH headers are omitted.
   The path to source the arch file should be adapted to the machine.
+  The execution line should also be adapted according to the set-up.
 
-# jobPEM.slurm:
-  Bash script file to run the PEM with a SLURM job. The name of the PEM executable file and Reshaping executable file should be adapted. The header corresponds to the ADASTRA supercomputer and should be changed for other machines.
+# PEMrun.job:

+  The execution line should also be adapted according to the set-up.
+  The PEM executable can have an optional argument to specify the SLURM job ID in order to detect the job time limit and deal with it.
