This is the first time I am asking question on Bioconductor and I am
not sure which address I should be emailing to. Hope I didn't send to
the wrong address.
Hi
I am using LimmaGUI at the moment to analyse quite a large dataset
which includes lucidea spiking controls. I realise that when I used
LimmaGUI to plot MA plot on individual slide with coloured legend,
everything is fine. However, when I made MA plot using linear modeled
data (on all 4 slides), there seemed to be colour distortion, i.e.,
the ratio controls will have the same colour as my genes etc. Do
anyone have any ideas to as how I can get around with it?
Also, as I am quite a new player with working with array data, I will
certainly appreciate if anyone can offer me any ideas to as what kind
of statistical tests should I do with array data if I am preparing
them for publications. Right now, I am just using the calibration
controls (none DE genes) in lucidea scorecard to arbitrary set cut
offs for DE genes. In most cases, the genes I termed as differentially
expressed will have good B, T and P values from LimmaGUI and some of
the genes had been verified to be DE. But are these (statistics)
enough for publication?
Thank you.
