I have 2 questions. I am very new in bioinformatics field. I am working on NCI-60 Cancer cell lines to find out miRNA and their target mRNA with computational methods by Machine Learning.
for the miRNA expression profiling in this sample http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM647461
there are ID_REF and value(normalized log2 expression) column. Can I use this value as expression value of each miRNA ?
again for the same sample the mRNA profiling here http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM133565 gives many columns ( ID_REF, CHPPairs, CHPPairUsed, Value, CHPDetection and CHPDetectionPvalue ).
which column can be used as the expression value of each mRNA (if possible) ?
Besides, if you give short notes or reference about those headers (CHPPairs, CHPPairUsed, Value, ...) it will be very helpful.
Thank you for reading :)
