Protocol publication

[…] Genome sequences representing the spatiotemporal distribution of CHIKV were downloaded from GenBank and aligned using MUSCLE [] and manually adjusted in Se-Al (available at according to amino acid sequence homology. The E1 region was then excised and combined with the 34 newly generated CHIKV E1 sequences, leading to a final data set containing 103 sequences and 1317 nucleotides. A maximum likelihood tree was then inferred using the PAUP v4.0b package [], based on the best-fit nucleotide substitution model determined by MODELTEST []. The database and operation script is available upon request from the authors. […]
