estMrkOrderGenDistsWithCarthagene | R Documentation |
Estimates marker order and genetic distances for a given linkage group with CarthaGene (commands "buildfw", "flips", polish" and "squeeze").

cg |
list returned by |
linkgroups |
data frame returned by |
lg.id |
identifier of the linkage group of interest |
keep.thresh |
the minimum difference in log-likelihood between the best insertion point and the second best insertion point required for the map to be considered in the future |
add.thresh |
the minimum difference in log-likelihood between the best insertion point and the second best insertion point required for a locus to be insertable; this threshold is also used to filter out the differences in log-likelihood reported by the post-processing option (only differences lower than the threshold will be reported) |
init.order |
if not NULL, vector containing at least three marker identifiers in a given order to start from |
postprocessing |
if 0, only framework mapping is performed; if 1, post-processing is also applied (see "add.thresh"); if 2, post-processing is applied only to markers in "mrk.list" |
flips.size |
size of the sliding window for the "flips" command (cannot exceed 9) |
flips.lod.thresh |
maximum difference of log-likelihood with the best map so that "flips" reports the permutation |
flips.iter |
if 1, "flips" will be iterated as long as a new, improved map has been found; specify O, otherwise |
squeeze.thresh |
distance threshold in cMorgan (Haldane distance) for genetics data or cRay for Radiation Hybrids data used by "squeeze" to expunge non-reliable locus from the map |
mrk2phy |
named vector which names are the locus and values are the physical distances on the chromosome corresponding to the linkage group of interest |
verbose |
verbosity level (0/1) |
data frame returned by parseCgMaprintd
containing the best map for the given linkage group according to CarthaGene, and possibly a column "physical.distance"
