 How to run it
 
 1. Be sure to have correct paths in local/dirs.inc for the different libraries
-2. You can compile from HeLaZ/ using make and launch from HeLaZ/wk using ./../bin/HeLaZ
-3. To have a better interface, open a script HeLaZ/wk/parameters*.m and run it to set up a wanted simulation.
-4. You can obtain various plots and gifs using HeLaZ/wk/analysis_2D.m once the simulation is done. To select the correct output file, run parameters*.m with the corresponding simulation parameters and then run analysis_2D.m (everything with matlab from wk/)
+2. Compile from HeLaZ/ using make
+3. To run the code, use HeLaZ/wk/local_run.m and run it to set up the parameters and the results folder
+4. Then go to the results folder and launch HeLaZ using mpirun -np num_procs ./../../../bin/helaz num_p num_kr

+// Comment : For some collision operators (Sugama and Full Coulomb) you have to run COSOlver from B.J.Frei first in order to generate the required matrices in HeLaZ/iCa folder.
