Hi,
I was wondering if anyone knows the difference between moe430a and
moe430av2
affymetrix chips.
The cdf packages that get automatically installed with them are are
moe430acdf and mouse430a2cdf respectively. The moe430a and moe430av2
chips
have the same number of probe sets, the same probe set names and the
first
65000 probe sequences (the ones I tested) are identical. I would like
to
make one expression set out of them so I can normalise all the chips
together, but I cannot do so presumably because of the different cdfs.
I can
bring them in separately but if I bring them in together I get the
following
error
Error in initialize(value, ...) : Cel file C:/Documents and
Settings/margar/Desktop/DairyCRC/Palani/430A/C_SO_QSI1A_MOE430A_160704
.CEL
does not seem to have the correct dimensions
Does anyone know how I might be able to get around this problem?
Any suggestions would be much appreciated.
Regards
Marg
