[R] Meta-analysis on microaray data, when a sinlge experiment contains diferent tissues

[Mohammadian]

Hi!

I dont know whether this is the best place to ask this question, however:

Suppose I want to perform meta-analysis on 10 different microarray studies.

Study	Tissue-source
Study1     Neuron
Study2     Blood
Study3     Neuron and PBMC
......
Study10   ...

How should I treat Study3?
The R package I want to use is among MetaMA, MetaDE, and perhaps crossMeta
Even a reference article/book/tutorial would be appreciated.

Thanks in advance
