At GYDLE inc., I work on optical mapping problems, and sometimes I find solutions to these problems. To tackle efficiently any problem, the error model for the problem must be understood. To write software that deals well with a given type of data, this type of data has to be understood, and one must be able to separate the good data from the bad data. Once in a while, I read scientific papers to keep myself up to date with the optical mapping technologies. I created a Mendeley group where I maintain a list of papers on optical mapping. The list is available here . Some of these papers describe error models for optical mapping.
