Hi Mohamed,

Please go through following paper on MEDME,
http://www.ncbi.nlm.nih.gov/pubmed/18765822

Wherein author has explained the way they have done data analysis. After reading if you need any help, please let me know.

Prashantha,



Thank you for your answer, MeDIP protocol is used  for our project! But
i have files in text format with ( Mean 635, Mean 532, Median
635,Median 532, .......) obtained from Agilent CpG islands.



I thought that Limma is adapted for this kind of file! I  looked at the
MEDME package, but i dont have the same kind of file ( GFF, SGR)

Can I change my text file in GFF file to run MEDME package?



Thank you again for your help Prashantha



Regards 

mohamed

        Dear Mohamed,

        

There are two ways to do methylation profiling, one with DMH and other
with MeDIP technique. Therefore it is better to provide information of
which method you use? In case, DMH, you can go ahead with Limma, as DMH
data is linear to methylation level, otherwise use MEDME, which takes
care of the non - linear nature of  methyaltion levels generated by
MeDIP technique.

Prashantha

          Dear R users,

          

I  try to use Limma package  to analyze methylation databases generated
          

from Agilent CpG Islanfds, but i dont know if this is relevant because 
          

i have 4 groups ( one replicate for each group) ??

Can you please  suggest me a method to analyze my data ?

          

Any help will be appreciated

Regards
