Gamma value is NA

[ericolo]

Hello again!

I managed to run my ~40K pangenomes and I'm trying to sort out which "worked" or not. For that I'm looking at the gamma value, and I was wondering what NA means ?

For example, this is what I got for a species with 16 genomes, in the rarefaction_parameters.csv file:

Looking at the distribution of the species size, it seems that the size of the largest pangenomes that has NA as the gamma value for the persistent genome is 16, and on the opposite side the smallest pangenome with a gamma value != NA also contains 16 genomes. So it seems 16 is the limit, but why is it that some worked and some didn't although they both contained 16 genomes ?

Does NA mean that the partitioning cannot be trusted ?

Thanks in advance !
