segfault in ADMIXTURE

Question

[jregalado]

Trying to run bootstrap computation in ADMIXTURE. Unfortunately I am getting a segmentation fault when computing bootstraps. Documentation for this program is terrible, author does not reply emails, and worst of all, code is not available. Why do people do this?

My main suspicion is that I am providing malformed input files as the test data works fine. Unfortunately as mentioned before, documentation provides no insight except that it expects plink's .bed or .ped files. Plink runs OK with my data.

I wish I could provide an error message to give more information about my error, but as mentioned before, I only get a segfault. I did run ADMIXTURE under valgrind, but with no source code, I can't debug the problem properly.

Thanks for any help

segfaults are mostly caused by not having enough memory available.

[jregalado]

Sure it's not memory related. I have nailed it down with something in the input as test data works fine.

Unfortunately segfault occurs only during bootstraping.

Source code not available and authors do not answer.

I'm having the same problem here. where you able to solve it?

segmentation fault can be results of not only memory issue but also invalid data type or interruption of main tool or a dependent tool installation. I suggest you check your input data first.
