When I run below command to subset the SNPs on a very wide range on chromosome 1, I get "Could not place marker for left window edge" error from PLINK.

plink --bfile mydata --chr 1 --from-kb 1000 --to-kb 200000

I read some other posts on Biostars asking the same question, and the responses are telling there may not be any SNPs in the specified range. However, the range I am specifying is too wide, and my prior information tells me that there should be many SNPs on that wide range on the largest chromosome 1.

Here is the PLINK output:

Reading map (extended format) from [ mydata.bim ]
7347235 markers to be included from [ mydata.bim ]

ERROR: Could not place marker for left window edge

I keep getting the same error when I use 1 or 10 instead of 1000 as the "from" kb.

I am completely stuck. Any help is welcome!
