However, you actually change two things here, namely both the specification of n.features/n.data and using 'format' vs 'column.info'. To help me figure out which of these two things causes the error, can you try running the remaining 2 combinations? I.e.: temp <- readCtData(files="Prueba_Blanco001.txt", n.features=96*96, format="BioMark") raw1 <- readCtData(files="Prueba_Blanco001.txt", n.features=96, n.data=96, column.info=list(flag=9, feature=5, type=6, Ct=7, position=1), skip=12, sep="\t") Thanks \Heidi > Many thanks in advance > > Juan > > --------------------------------------------------------------- > Juan Fernandez Tajes, ph.
