Hello all, I am trying to upload my CEL files using the function ReadAffy with the widgets option and I keep getting an error message (I have used in order to install BioC what I believe is the latest version of the available script _getBioC version 1.2.29_ from http://www.bioconductor.org/getBioC.R I have also installed ActiveTcl8.3.5.0-2-win32-ix86.exe and when prompted in R: > library(tcltk) all seems to be OK. This is the error message: > alldata <- ReadAffy (widget=TRUE) Error in structure(.External("dotTcl", ..., PACKAGE = "tcltk"), class = "tclObj") : [tcl] ambiguous option "-col": must be -column, -columnspan, -in, -ipadx, -ipady, -padx, -pady, -row, -rowspan, or -sticky. Could anybody tend a helping hand here? Thanks so much, Fatima _______ ? ?
