I have tried clustal amd muscle both program for alignment and also tried older version of MEGA but the error remains. please let me know how to solve this problem.

Hi Shahirina,

I am writing in response to your question regarding the MEGA software. The error you encountered indicates that your data has some sequence pairs for which it is not possible to calculate distances using the specified settings. You should inspect your data to identify and remove the offending pairs.
