    Dear Pasi Rastas:

    I noticed that there is an option "removeMarkers" that can be used to remove markers from further analysis in SeparateChromosomes. What are the appropriate marker identifiers for LM2 to recognize?

    Thank you,
    Qifan

      It is a list of numbers x y z e.g. removeMarkers=1 100 10003. You need to know which markers to remove.

        Dear Federico Calboli,

        I ran OrderMarkers with 1,900 markers from one linkage group, the results indicated that the likelihood score is negative (-3929), is it normal?

        Also, I noticed there are some markers with high error estimate (>0.4 or <-0.4) and around 700 duplicate markers in the order file. If I want to filter out these markers to improve the order accuracy with evaluateOrder, do I need to use "removeMarkers" option or the "OrderMarkers" module will recognize and remove them automatically (with "minError=0.4" option)?

        Thank you,
        Qifan

          That’s for Pasi to say

          much easier to remove all that stuff using a bash script

          awk '($5<=0.01)' yourmap.txt |cut -f 1| head -n -1> yourmap2.txt
          [add some grepping off the duplicated markers — please note I never remove them]

          java -cp OrderMarkers data=yourdata.linkage alpha=0 evaluateOrder=yourmap2.txt improveOrder=0 > yourmapfinal.txt

          Thank you,

            All right, Thank you! So only the first column of the order file is used by the "OrderMarkers" module.
