Hi Henrik, I've ran the entirety of the vignette up to the same point (I did forget to run the fit(plm, verbose=verbose) and the same error persists.
The reason I'm using version 1 is because all we need is the raw copy number so we didn't need any of the additional tools/calculations. traceback() 8: throw.Exception(Exception(...)) 7: throw(Exception(...)) 6: throw.default("Cannot fit target function to enzyme, because there are no (finite) data points that are unique to this enzyme: ", ee) 5: throw("Cannot fit target function to enzyme, because there are no (finite) data points that are unique to this enzyme: ", ee) 4: getTargetFunctions.FragmentLengthNormalization(this, verbose = less(verbose)) 3: getTargetFunctions(this, verbose = less(verbose)) 2: process.FragmentLengthNormalization(fln, verbose = verbose) 1: process(fln, verbose = verbose) sessionInfo() R version 2.11.1 (2010-05-31) powerpc-apple-darwin9.8.0 locale: [1] en_US.UTF-8/en_US.UTF-8/C/C/en_US.UTF-8/en_US.UTF-8 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] preprocessCore_1.10.0 aroma.affymetrix_1.6.0 aroma.apd_0.1.7 affxparser_1.20.0 R.huge_0.2.0 [6] aroma.core_1.6.0 aroma.light_1.16.0 matrixStats_0.2.1 R.rsp_0.3.6 R.cache_0.3.0 [11] R.filesets_0.8.1 digest_0.4.2 R.utils_1.4.0 R.oo_1.7.2 R.methodsS3_1.2.0 loaded via a namespace (and not attached): [1] tools_2.11.1 print(ces) yields: CnChipEffectSet: Name: Mcels Tags: QN,RMA,A+B Path: plmData/Mcels,QN,RMA,A+B/GenomeWideSNP_6 Platform: Affymetrix Chip type: GenomeWideSNP_6,Full,monocell Number of arrays: 4 Names: GM6, GM7, GM8, GM9 Time period: 2010-06-04 16:10:31 -- 2010-06-04 16:10:36 Total file size: 107.80MB RAM: 0.01MB Parameters: (probeModel: chr "pm", mergeStrands: logi TRUE, combineAlleles: logi TRUE) -- When reporting problems on aroma.affymetrix, make sure 1) to run the latest version of the package, 2) to report the output of sessionInfo() and traceback(), and 3) to post a complete code example.
