What is the structure of the data in "baseline.dat"?
The [[{1,2},All]] will grab the first two rows and all columns
of the data in "baseline.txt". Is that the structure? That is
you have multiple columns and only want the first two rows?
Perhaps you meant to get the first two columns in
"baseline.dat". If so, the [[{1,2},All]] should be [[All,{1,2}]]
Do you get what you expect if you do
Dimensions@ReadList["baseline.dat",Number,RecordLists->True]
