Hi all, I was following the tutorial flowWorkFlow.pdf to analyze flow cytometry data and I have the following problem: when I launch: > qp1 <- qaProcess.marginevents(flowData, channels = c("FSC-A", + "SSC-A"), outdir = dest, pdf = TRUE, sum.dimensions = c(5, + 3)) R say: computing margin events... Error in strsplit(iInf, " ")[[1]] : subscript out of bounds sh: identify: command not found I have already tried to reinstall R with no success... any suggestion? My system is: MAC OS X 10.6.4 Intel Core 2 Duo (64-bit) Identify location: which identify /opt/local/bin/identify my $PATH: echo $PATH /Users/drambald/bin:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/ sbin:/sbin:/usr/local/bin:/usr/texbin:/usr/X11/bin Any suggestion to fix it ?
