The new readGenotype prints "Original size: 1 and read-size is 512".
My species are the same, I only have one subpopulation. Everything is
No rush, I totally understand about GECCO's deadline.
A little quote from my parameter file:
pop = ec.Population
pop.subpops = 1
pop.subpop.0 = ec.Subpopulation
pop.subpop.0.species = ec.gp.GPSpecies
pop.subpop.0.species.ind = ec.gp.GPIndividual
pop.subpop.0.species.ind.numtrees = 1
pop.subpop.0.species.ind.tree.0 = ec.gp.GPTree
pop.subpop.0.species.ind.tree.0.tc = tc0
