Hi Victoria,

HTqPCR is currently at version 1.11.2, so I assume you mean the
version
corresponding to R 2.10. It's not maintained as such, but it's still
available at
http://www.bioconductor.org/packages/2.10/bioc/html/HTqPCR.html
and I can think of no reason as such why it wouldn't still work.

Hm, can you be a bit more specific here?

How are you actually reading in the file? I.e., what's the exact
readCtData command you provide? Are 'test' and 'reference' supposed to
be
the gene classes? It sounds like they're all labelled 'target' per
default, because the information about which column to use isn't
passed on
to readCtData.
If you look at the documentation for readCtData, you may notice that
if
the parameter format="BioMark" is used, then the columns being read in
are:
column.info=list(flag="Call", feature="Name.1", position="ID",
Ct="Value")
So, per default no column is being read that specifies the 'type' of
gene,
which I suspect is what you're after. This is intentionally left
blank,
since not all Fluidigm files contain a column with this information or
the
column name changes.
You may try using readCtData with your own information specified, i.e.
column.info=list(flag="Call", feature="Name.1", position="ID",
Ct="Value",
type='INSERT YOUR OWN VALUE HERE')
If this doesn't work, then gimme a shout, preferably including the
exact
commands you tried.
Best,
\Heidi
