Thank you Henrik, It works now, but I got some warning: process(ce, verbose=TRUE); Generating ChromosomeExplorer report... Loading required package: Cairo Generating ChromosomeExplorer report...done [1] TRUE Warning messages: 1: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, : there is no package called 'Cairo' 2: In method(static, ...) : Ghostscript not found. Searched directories: C:/gs, C:\Program Files/gs, /gs, C:\Program Files\Common Files/gs
Are those warning messages serious? Could I ignore them?

Try reinstalling the program > to fix this program. I can reproduce this on 64-bit Windows 7 - you get the same error if you try library("GLAD"). It is because we utilize part of the GLAD package, if and only if it is *installed*, and otherwise we turn to backup solutions. What happens here is that *GLAD is installed but doesn't load*, which causes the error so that backup solutions doesn't kick in. In the next release I'll try to make sure the backup solutions will also work when there is an error load GLAD. In meanwhile, you can do this: WORKAROUND: 1. Uninstall the GLAD package (it doesn't work anyway): > remove.packages("GLAD") Removing package(s) from 'C:\Users\hb\R\win-library\2.12' (as 'lib' is unspecified) > library("GLAD") Error in library("GLAD") : there is no package called 'GLAD' That should do it. Let me know if it works for you. TECHNICAL DETAILS: It happens because the GNU Scientific Library (GSL) is not installed on the system (hence the 'gsl' part of 'libgsl-0.dll'). There is a hard-to-find note that you need GSL in order to use the GLAD package, cf. http://bioconductor.org/packages/release/bioc/html/GLAD.html. There exist 32-bit binaries of GSL at http://gnuwin32.sourceforge.net/packages/gsl.htm. Unfortunately, it does not work for the 64-bit version of R on Windows 64-bit. It works if you do tricks an run the 32-bit version of R, but that is a rather inconvenient workaround. /Henrik > > > Yan > > -----Original Message----- > From: aroma-affymetrix@googlegroups.com > [mailto:aroma-affymet...@googlegroups.com] On Behalf Of Henrik Bengtsson > Sent: 23 November 2010 18:50 > To: aroma-affymetrix > Subject: Re: [aroma.affymetrix] libgsl-0.dll missing error > > Hi. > > On Tue, Nov 23, 2010 at 10:05 AM, Yan Jiao <y.j...@ucl.ac.uk> wrote: >> >> >> Dear all, >> >> I'm trying to do DNA segmentation, >> >> This is what I'm doing: >> >> ds <- doCRMAv1("Fockens_1", chipType="Mapping50K_Hind240", > verbose=TRUE); >> >> ###this is done sucessfully >> >> # Segmentation >> >> cbs <- CbsModel(ds); >> >> >> >> I got error libgsl-0.dll is missing, I think it's using GLAD, but I'm > trying >> to use DNAcopy for segmentation. > > Is it really the case that you get that error when you do: > > cbs <- CbsModel(ds); > > or do you do anything else?
