Calculating Contact enclosures by METAL

Hi All,

I am using ICADVM20.1 version. I have a flat layout database. I want to calculate the enclosures of a contact with metal. I also want to check both sides of the enclosures. If they are below my expected values, I should have the database ID of the contacts that do not meet the enclosures.

Below is My code 

abeInit(cv=geGetEditCellView())
M1=abeLayerFromCellView("MET1" ?purpose "drawing")
CO=abeLayerFromCellView("CONT" ?purpose "drawing")
abeLayerGrow(CO COgn=abeNewLayer() ?north 0.06 ?south 0.06 ?east 0.015 ?west 0.015)
abeLayerAndNot(COgn M1 M1COgn=abeNewLayer())
abeLayerToCellView(M1COgn "marker" ?purpose "error")
abeDone()
Markers=setof(x cv~>shapes x~>lpp==list("marker" "error"))
filterM=nil 
printf("test1") 
foreach(x Markers 
b=x~>bBox 
y1=yCoord(upperRight(b)) 
y2=yCoord(lowerLeft(b)) 
when(y2-y1>-0.035 printf("test") 
filterM=cons(x filterM))
) 
printf("\nTest")
foreach(x filterM geSelectFig(x))

In this code I am trying to create markers which have not met the enclosures of MET1 so that I can convert the markers into MET1 shapes.
But I am getting lots of markers created so they are raising some more DRC's

Can anyone help me?

Thanks in advance
Teja.
