It depends with the number of populations you want to analyze. If you have few populations >15, it is better to set up to K=15 then you can use Evanno method/ structure harvester to determine the most probable K.I didn't get on what interaction level you want to determine, but you can set an admixture parameter, and the program will run the admixture algorithm which will get assorted in the membership coefficients output values and you can visualize through the image (using Distruct software).

Thanks Charles.

Actually I am running programme smoothly but in the result files are empty at the end of the simulation. I tried both window 7 and 8 for running structure version 2.3.3 and 2.3.4 but the problem is still there. The data file I prepared as a binary matrix and species is assumed haploid input format is when uploaded with structure and programme were set with length of burning period 20000 and number of MCMC100000, using Admixture model with correlated allele frequency assuming set of population of 10. I set K=2 to K=10 the programme run smoothly but I could not get result file even after so many change. Kindly suggest what is needed to be done exactly

Thanks Charles. One more thing want to share that I am getting the value of Ln Like= --- and Ln PD = 0 is this the reason of no results. and if this the reason then how I can remove it

Sorry Arun for that problem, for sure is frustrating. In the beginning while your setting parameters, have you identify the folder where your result will be saved. The Ln prob column should have values. Or what kind of the input data file you have, might be not compatible with the settings. I am not much conversant with the haploid data, I am much used to diploid data set. I have the feeling that something could be wrong with the parameter settings or the format of the input data file.

For K max = 10 is okay , especially if the population are not much different to each other, then could expect the most probable K could be below 7 even lower. May be you may try to run through structure Harverster direct on the web. http://taylor0.biology.ucla.edu/structureHarvester/

Thanks

Charles for your suggestion and guidance. I will soon come back with further question and progress

Your always welcome Dr. Arun. Wishing you the best.

Hi Dr. Charles

Still struggling with the empty result file do you have any idea in this reg
