I have a copy number segment file with this by SCAT R package
Chromosome Start End
1 10583 120983
1 121009 245455
1 404187 5719467
1 5719471 5735807
I want to count the number of markers in these locations
I asked somebody how to do this, he replied:
We created marker file by dividing the genome into 10 kb bins, so the markers file contains the start and stop positions for each of these 10kb segments for each chromosome along with ASCAT segments start and end positions. Then, for each ASCAT copy number segment, we count how many markers fall within that region for total probes.
Can somebody helps to understand what he mean by dividing the genome
