Dear bioconductors I'm trying to use the OneChannelGUI package to analyze some exon arrays experiment... After succesfully normalized, filtered, computed MIDAS and SI index of my array, now I'm trying to use the function inspecting splicing indexes(on the midas alternatively spliced probes detected) to obtain gene level and exon level probeset ids for my alternatively spliced exons (then I'd use them to identify the Isoform for the alternative splicing event) as in the manual is mentioned. Everytime I try to use the inspecting splicing indexes function I retrieve always the same error: Error in xy coords(x,y,xlabel,ylabel,log) x and Y lenghts differ. Someone could give my any suggestion? Is there something wrong in what I do?
