Dear Hua Hao and René,
I was not aware of that use of eABF in multiple-walker form in the
tutorial. That is not a documented/supported feature, and there is a little
work to properly combine the data.
Anyway, I have just pushed a commit that partly reverts the previous one.
What remains is that ABF files are written after sharing, so the plain ABF
data should be the same for all replicas.
Best regards,
Jérôme
