Is there any tool for defining the tumor cell purity in gene expression microarray data?
Thanks in advance
Have you searched the World Wide Web? There appears to be solutions for methylation arrays.
You might need to clarify what kind of array that you are talking about. Like methylation, expression, or SNP chip.
Hi- If it's genotyping arrays you are referring to, then you could try ASCAT. ASCAT is designed to detect copy number variants and it gives, in addition, the purity estimate.
