Hello,

I want to know if I can do something on galaxy. I have a folder for the chromosome 1 with start of G4 and start of ORI. For each start G4 I associated all of start ORI. For example if I have 2 start G4 (2 lines) and 4 start ORI (2 lines), I will have on a new file 8 lines.

startG4-1   start ORI-1

startGA-1   startORI-2

startG4-1   startORI-3

startG4-1   startORI-4

startG4-2   startORI-1

startG4-2   starORI-2

startG4-2   startORI-3

startG4-2   startORI-4

Now I do the difference between the first column and the second and I want the absolute value of this difference to have the distance between the start G4 and the start ORI. I obtain a third column.

Now that I want is the minimum of those absolute values. And I want to know which start G4 and which start ORI who correspond to this mimnimum.

For example if the minimum of startG4-1 is on the third column and the minimum of startG4-2 is on the second column. I want as result

startG4-1   startORI-3   min(c2-c1)

startG4-2   startORI-2   min(c2-c1)

So know my question is, do you know if I can obtain that I wnt on Galaxy, and if YES how?

Best regards,
