Hi all,

I'm having trouble getting R to read in my aCGH log2.ratio data.  I am using

I notice that the example files are tab-delimited with "\n" as newlines.
These work fine when read by R as R is able to differentiate samples columns
from Well_ID columns (aka Target).  I'm creating my files from excel and
saving as tab-delimited TXT, but R reads every column as a sample, including
the Well_IDs.  Can someone help?

For the sample files,
num.samples(ex.acgh) outputs 2
whereas with my dataset it outputs 3

Thanks for the help!
