Primary options: Sequences (either FASTA format* or one sequence per line, single letter code)**. * Sequence names from the FASTA will be placed in the middle of helical wheels. ** Use '%' to produce an "empty" position (cirle with no letter) and a '#' to skip drawing a position. Starting heptad position: a b c d e f g Parallel Anti-parallel Mixed (for higher-order oligomers) For each chain after the first one, specify 1 if it is parallel to the first chain or 0 otherwise.
