Any format annotation (eg. fasta header) shall be removed.
Each strand shall be labeled with ">" and "<",
and the residue on the midplane shall be labeled with "|" and "|".
For example, "...KDNT>WYTG|A|KLGW<SQY...." is a properly labeled sequence of a strand,
where ">" marks the start of the strand, "<" the end of the strand,
and residue between the two "|" (A in this case) is the one on the midplane.
The OPM server
is recommended to
determine the position of midplane. Alternatively, you may make a guess of its position,
since our algorithm does not require an accurate position of midplane.
But be aware the results in this case might not be as accurate.
Please note that the seq id is the number of the residue of interest in the sequence entered below,
not necessarily the same as the one in a pdb file.
