Hi, I have been using aroma to analysis our SNP6.0 array for a while. Now we got data on the Mouse diversity array (MouseDIV__m520650).
I ran into problem at the fragmentation length normalization step -- same as http://www.mail-archive.com/aroma-affymetrix@googlegroups.com/msg01458.html: Error in list(`process(fln, verbose = verbose)` = <environment>, `process.FragmentLengthNormalization(fln, verbose = verbose)` = <environment>, : [2011-01-13 14:31:10] Exception: Cannot fit normalization function to enzyme, because there are no (finite) data points that are unique to this enzyme: 1 at throw(Exception(...)) at throw.default("Cannot fit normalization function to enzyme, because there a at throw("Cannot fit normalization function to enzyme, because there are no (f at normalizeFragmentLength.default(y, fragmentLengths = fl, targetFcns = targe at normalizeFragmentLength(y, fragmentLengths = fl, targetFcns = targetFcns, s at process.FragmentLengthNormalization(fln, verbose = verbose) at process(fln, verbose = verbose) 20110113 14:31:10| Normalizing log2 signals...done 20110113 14:31:10| Array #1 of 36 ('KP_17124_NT_MOUSEDIVm520650')...done 20110113 14:31:10|Normalizing set for PCR fragment-length effects...done I am just wondering if there is any update on this issue. Thanks, Yupu -- 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.
