Keeping A Subset Of Data For Qc

I am using putty to run plink for this data analysis.

I have been asked to perform a QC on a subset of data from a given dataset. I have used the command to keep the data (plink --bfile data --keep mydata.txt) and it has saved the necessary files as a .txt file.

When I enter (plink --file mydata --maf 0.05) it states that no mydata.ped file exists?

How do I overcome this problem?

plink maf

We'll close it then.

Rename mydata.txt to mydata.bed.

Changing it to mydata.bed then prompts it to say: ERROR: No file (mydata.bed) exists
