Important usage notes:
The main application scenario for FluSurver is to highlight phenotypically or epidemiologically interesting candidate mutations for further research and should ideally be combined with experimental testing and verification of any predicted phenotypes. Importantly, any direct diagnostic use, assumed severity or recommendation on patient treatment should not be based solely on these computational predictions. Our curated reference sequences used for annotation transfer of equivalent mutations are mainly comprised of strains that recently infected humans. Therefore, the usage scenario that will give the most fruitful and reliable results are current surveillance sequences with very close relation to used vaccine strains, including some candidates for avian flu (including H5N1, H5N6, H5N8 and H7N9) and novel reassortant swine flu H3N2v.
Please take a look at the Frequently Asked Questions and Tutorial if you are new to FluSurver. You could also look at this NA drug susceptibility example analysis walkthrough starting from GISAID and the GISAID access summary poster

The server can automatically determine the type of input (either protein or nucleotide) and the closest reference sequence among current
vaccine strains to compare.
Also mixtures of genes/proteins (e.g. HA and NA or all genes of the same patient) can be provided as input.
