Before pairing round 1, you must decide how to assign the starting rank numbers (pairing numbers).
Depending on the pairing system, you may choose one of the automatic drawing methods. For Monrad/konrad tournaments you use either seeded drawing or random drawing. For round-robin tournaments only random drawing. applies. In swiss-type tournaments, the numbers are assigned according to rating and other criterias.
Alternatively you may assign the numbers youself using any method you like, and enter the numbers manually in the appropriate field. Select manual draw to have TS checking your entry for errors..
