TreeMix input throws terminate called after throwing an instance of 'std::logic_error' error

[hemr3]

Hi, apologies if this is not the right way to get in touch regarding this issue.

I have attempted to do this command:

treemix -i data.p.treemix.gz -o output

And this results in the error:

WARNING: no counts at SNP 3318 population 0 Estimating covariance matrix in 3336 blocks of size 1 SEED: 1620902211 terminate called after throwing an instance of 'std::logic_error' what(): basic_string::_M_construct null not valid Aborted (core dumped)

The input file seemed to be correct:
DEN NEA 2,0 0,2 0,2 2,0 ...
With each population having two individuals (in a tabular format).

The data is aDNA, and thus has a high level of missingness. I have then removed the missing SNPs from the input file, and it still results in the same error.

If you have any advice for me regarding this, I'd be very grateful.

I am bumping this question as I am having a similar issue. I don't suppose you found a solution @hemr3 ?

Following up my response here, which may help you (three years later), my issue was with population names. In my header, mine did not contain spaces or any non-typical characters (except underscores, where I tried with and without them and got the same result), but when I rewrote out my pop names as 'one, two, three...etc.', everything worked perfectly. I assume simple pop names is the solution. Hopefully this will help someone else in the future.
