I used command ./kmergenie <filename.fastq> running histogram estimation Setting maximum kmer length to: 251 bp computing histograms (from k=21 to k=121): ntCard wall-clock time over all k values: 0 seconds fitting model to histograms to estimate best k could not predict a best k value No best k found

Do i need to change the k value to less than 21? How can I obtain the best K value for my reads?

sorry for wrong response. well I did not install R which is a prerequisite for kmergenie. I installed it and ran the command make again.

If it took zero seconds, it appears that there was probably zero input, so you may want to examine the input file and make sure it was non-empty. That said, if you want to find the optimal kmer length for assembly, I suggest you read this post.

This is not an answer to the question. It's useless to anyone searching this problem to see that you fixed it without saying what happened. It would be courteous to tell us what was going wrong or what you found.
