plink marker error

[roll]

Hi,
I keep getting the following error message from plink:

ERROR: Could not place marker for left window edge

Does anyone know what does this error means?

I am using the options --from-bp and --to-bp

Thanks in advance

It means it could not find your --from-bp marker name. Double-check your spelling and whether you have the correct files.

Everything seems fine. I have a center point and i would like to get the association results within a certain window. So i added 100bp to get the --from-bp parameter and subtracted 100bp to get the --to-bp parameter. Do you think there is something specifically wrong at that position? if yes, how can i check that position specifically?

Oops, my last response confused --from with --from-bp.

Anyway, the only way I've been able to get the "left window edge" error message is by providing --from-bp with a position value larger than the last actual bp position on the chromosome. So, two things to check:

- Are you actually using --from-kb or --from-mb when you meant --from-bp?
- Is your .bim file missing bp positions? Check the fourth column.
