Hi list, I am having trouble with the parameters method in flowCore. When applying parameters to an element of multipleFilterResult generated by a tmixFilter, R will throw the following error: Error in x$parameters :$ operator is invalid for atomic vectors This came up while trying to apply an other filter to the result of a tmixFilter. Best, Bastian Angermann Here's how to reproduce the error (R 2.9.0 flowCore SVN 39752 /flowClust SVN 39598): data(GvHD) fcsData <- GvHD[[1]] tmixGate <- tmixFilter(parameters=c("FSC-H","SSC-H"), K=1) recGate <- rectangleGate(.gate=list("FSC-H"=c(0,1000),"SSC-H"=c(0,1000))) rf <- filter(fcsData,recGate) tf <-filter(fcsData,tmixGate %subset% rf ) > tf A filterResult produced by the filter named 'tmixFilter in defaultRectangleGate' resulting in multiple populations: 1 > class(tf) [1] "multipleFilterResult" attr(,"package") [1] "flowCore" > parameters(tf) [1] "FSC-H" "SSC-H" > parameters(tf[[1]]) Error in x$parameters :$ operator is invalid for atomic vectors -- GRATIS f?r alle GMX-Mitglieder: Die maxdome Movie-FLAT!

Hi Bastian, I just fixed this issue in the devel branch. Note that you will need to update both flowCore and flowClust. There have been substantial changes to the way things were handled compared to the previous release, so it would be tedious to port this fix back into the release branch. In the meantime, evaluating this before calling the parameters method should fix the issue in a sort of hackish way: setMethod("parameters", signature=signature(object="filterResult"), definition=function(object) unique(unlist(sapply(filterDetails(object), function(x) if(is.list(x)) x$parameters)))) Thanks for reporting the issue, Florian Bastian Angermann wrote: > Hi list, > > I am having trouble with the parameters method in flowCore.

I've updated flowCore/Clust to SVN revision 40494/40493. There is a minor issue with the read.FCS function: > read.FCS("../data/Yoav/HDM013 V2 1005 NS no.fcs") Error in sprintf("0,%d", pData(params)[p, "minRange"]) : use format %f, %e, %g or %a for numeric objects I've fixed this by replacing the %d by %g.

Could you point me to the file where this needs to be fixed. I couldn't grep it in the code. On 03.07.2009, at 09:18, Bastian Angermann wrote: > sprintf("0,%d", pData(params)[p, "minRange"])
Sorry, that's in the read.FCS function in IO.R line 144. -------- Original-Nachricht -------- > Datum: Mon, 6 Jul 2009 12:54:12 -0700 > Von: Florian Hahne <fhahne at="" fhcrc.org=""> > An: Bastian Angermann <angerb at="" gmx.de=""> > CC: bioconductor at stat.math.ethz.ch > Betreff: Re: [BioC] flowCore::parameters > Could you point me to the file where this needs to be fixed.
