I have a dataset per patient of results from array-CGH resulting from the ADM-1 software in the form:
AberrationNo Chr Cytoband Start Stop #Probes Amplification Deletion pval Gene Names
Are these data already segmented? Or do I have to implement an algorithm to do so? And if my data are already segmented, would an algorithm like CGHregions from Bioconductor be of use to reduce the number of regions?
I am sorry if these are basic questions, but I am new to Bioinformatics...
