... Hello Tim,
I tried your first suggestion (for chromosome 1). I got an error
message as
shown below:
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines,
na.strings,
:
line 2134 did not have 2 elements
Did you see something like this at your end?
Thanks,

... Hello Tim,
Thanks for the reply. I think this will give the 3'UTRs of all the
genes in
chromosome 1. How can I get this for ALL the genes in ALL the
chromosome
instead of repeating the step by changing the chromosome number?
Thanks a lot once again.

I am trying to download the 3'UTR sequences of all human genes from
Ensembl
Biomart using the package biomaRt. Ideally, after retrieving I want to

Comment:
C: AgiMicroRna and Replicates
... Dear Steve,
Thank you for your reply. I have done microarray experiments with
pooled
samples instead of replicates. I wanted to know if there is any
technical
difficulty in AgiMicroRna if we have no replicates.
Thanks,
Karthik
