Hi Henrik, Thank you very much for your response. However, I tried the following codes to set the minimal number of marker to 5, but the results I got still contain segments with only 2 markers ...
cbs = CbsModel(ds); cbs$.calculateRatios = FALSE; ce = ChromosomeExplorer(cbs); process(ce,chromosomes=c(1:23),min.width=5); I am not clear where I should put "min.width=5"? If I do "process(cbs,min.width=5)" first, how can I send the results to be displayed by chromosome explorer? Thanks again for your help. I look forward to hearing from you soon.
