         caption.css="color: gray; font-size: 9pt",
         caption="Produced by <a href=http://thegrantlab.org/bio3d/>Bio3D</a>",
         fontsize="11pt", bgcolor=TRUE, colorscheme="clustal")

Arguments

aln

an alignment list object with id and ali components, similar to that generated by read.fasta.

file

name of output html file.
