The chromosome band track represents the approximate location of bands seen on Giemsa-stained chromosomes at an 800 band resolution.
Barbara Trask, Vivian Cheung, Norma Nowak and the rest of the BAC Resource Consortium used fluorescent in-situ hybridization (FISH) to determine a cytogenetic location for large genomic clones on the chromosomes. For more information about the BAC Resource Consortium, please see "Integration of cytogenetic landmarks into the draft sequence of the human genome", Nature, vol 409, Feb. 2001, pp.953-958 and the accompanying web site Human BAC Resource.
Wonhee Jang and Arek Kasprzyk helped determined the location of these clones on the October assembled draft human genome using the clone sequence where possible and in other cases by STS marker and BAC end sequence locations. Clone placements are now being determined at UCSC using the same information.
Terry Furey and David Haussler developed a program which uses a hidden Markov model (HMM) to integrate the range of bands associated with various FISHed clones into the most probable arrangement of bands on the sequence given the assumptions of the model.
