This is equivalent to about 16000 positions (physical positions only)
or about 8000 positions (marker name and physical positions) depending on length of marker names.
This application allows interpolation of map positions on the Rutgers second-generation combined linkage-physical map (Rutgers map v.2). This resource allows you to determine cM-scale linkage-based map positions for any marker, given only its physical position. We are currently working on the map interpolator for Rutgers Map v.3.
NOTE #1: The interpolator function uses our smoothed v.2 maps (Build 36). This means that map positions from our interpolator are only in-scale with our smoothed maps, not with our raw maps. If you are using the interpolator to look up some map positions (say for markers that are not on our maps), and you are using our map files to look up positions of markers that are on our maps, you must use our smoothed map files to obtain consistent map positions.
NOTE #2: The Rutgers Map v.2 uses Build 36 coordinates. To convert physical positions from previous builds we recommend the UCSC liftOver tool.
Our lab is happy to assist with your project. Please contact us if we can be of any help - converting from other linkage maps or from other genome builds, or performing large-scale conversion or interpolation. Please e-mail us with suggestions for additional features that would be useful to improve the utility of our maps.
