Hi Jérôme,
I'm not talking about of a new simulation, I'm using the input files of the tutorial, actually I use the example-output files to build the map. I merged the outputs I then I run abf_integration following the instructions of the tutorial. In this map the C7ax spot have around 3 kcal/mol more than the alphaL area.
Best,
Carles.
