That's possible Kenanga from my point of view. You can make a matrix of rows and columns representing the frequent occurrences of your taxa in the studied samples. Then you can proceed with multivariate data analyses to achieve your goals. If you send me this matrix I can help you to choose the suitable techniques according to your goals of your study. If you welcome my collaboration you may send me your email address to start working. Best regards. Ashraf
