moving a single marker to a chr without knowing the position

[Steven Schneider]

Hello - easy question I hope.

When I performed "lodint()" with drop=1.5, I discovered that one of the markers (which are named for the chr on they were discovered) was possibly out of place, i.e. "marker_chr3" was at a location on LG/chr 10. 

I want to move the marker to LG/chr 3, but do not know where to put the position.

movemarker(cross, "marker_chr3", 3, ??) 

How do I get it to chr 3 and put in the best location?

Thank you!

Use the function tryallpositions().

Thank you - 

Is this just telling me where it best fits and then I use movemarker() to actually move from chr 10 to 3? Or is it better to manually move it in the data file? 

Thanks

Yes, use tryallpositions to determine where the marker belongs, and then either use movemarker, or create a corrected data file. Personally, I’d probably want to create a corrected data file.
