Genetic linkage analysis is a statistical technique used to map
genes and find the approximate location of disease genes. There
was a standard software package for genetic linkage called
LINKAGE. FASTLINK is a significantly modified and improved
version of the main programs of LINKAGE that runs much faster
sequentially, can run in parallel, allows the user to recover
gracefully from a computer crash, and provides abundant new
documentation. FASTLINK has been used in over 1000 published
genetic linkage studies.
You do not really need these papers about fastlink but it is highly
recommended to study this documentation before starting with the
tools of the fastlink package.
