hello.... i am using affymlmGUI for microarray analysis and finally i got top 50 genes which are up regulated. i got a file in which *ID M A t P.value and B *column are present. can anyone tell me what is M and A??? regards deepika [[alternative HTML version deleted]]

Hi Deepika, • M : log di!erential- expression ratio (log fold change) • A : the average log intensity Best wishes, S On 6 September 2012 14:13, deepika lakhwani <lakhwanideepika@gmail.com>wrote: > hello.... > > i am using affymlmGUI for microarray analysis and finally i got top 50 > genes which are up regulated. i got a file in which *ID M A t > P.value and B *column are present. can anyone tell me what is M and A??? > > > regards > deepika > > [[alternative HTML version deleted]] > > _______________________________________________ > Bioconductor mailing list > Bioconductor@r-project.org > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: > http://news.gmane.org/gmane.science.biology.informatics.conductor > -- Dr. Suparna Mitra Wolfson Centre for Personalised Medicine Department of Molecular and Clinical Pharmacology Institute of Translational Medicine University of Liverpool Block A: Waterhouse Buildings, L69 3GL Liverpool Tel. +44 (0)151 795 5394, Internal ext: 55394 M: +44 (0) 7511387895 Email id: smitra@liverpool.ac.uk Alternative Email id: suparna.mitra.sm@gmail.com [[alternative HTML version deleted]]

Dear list, I have done a gsea analysis, There are two groups: patient and control. I made a mistake by take patient group as control group. Do I have do the gene set enrichment analysis again or just could use the results I have by change the positive value such as enrichment score to negative value(like 2.3 to -2.3)? I mean do these statistics have same absolute value? Thank you. Best regards, Yong [[alternative HTML version deleted]]
