Hi, Is there a problem with the latest release of the moe430a annotation package or am I having problems installing it on my computer? I am running R2.3 on Mac OSX. I downloaded the source file for the latest version of the moe430a (moe430a_1.12.0.tar.gz) and tried to install it from the R menu. When I do library(moe430a), and moe430a(), I get the following output, which shows that something is not quite right. > library(moe430a) > moe430a() Quality control information for moe430a Date built: Created: Sun Mar 26 00:22:20 2006 Number of probes: 22690 Probe number missmatch: moe430aACCNUM; moe430aCHRLOC; moe430aCHR; moe430aENZYME; moe430aGENENAME; moe430aGO; moe430aLOCUSID; moe430aMAP; moe430aPATH; moe430aPMID; moe430aREFSEQ; moe430aSUMFUNC; moe430aSYMBOL; moe430aUNIGENE Probe missmatch: None Mappings found for probe based rda files: moe430aACCNUM found 14445 of 22690 moe430aCHRLOC found 13770 of 22690 moe430aCHR found 14345 of 22690 moe430aENZYME found 1933 of 22690 moe430aGENENAME found 14337 of 22690 moe430aGO found 13003 of 22690 moe430aLOCUSID found 14369 of 22690 moe430aMAP found 13920 of 22690 moe430aPATH found 4186 of 22690 moe430aPMID found 14317 of 22690 moe430aREFSEQ found 14174 of 22690 moe430aSUMFUNC found 0 of 22690 moe430aSYMBOL found 14350 of 22690 moe430aUNIGENE found 14310 of 22690 Mappings found for non-probe based rda files: moe430aCHRLENGTHS found 21 moe430aENZYME2PROBE found 616 moe430aGO2ALLPROBES found 5819 moe430aGO2PROBE found 4164 moe430aORGANISM found 1 moe430aPATH2PROBE found 171 moe430aPFAM found 12135 moe430aPMID2PROBE found 75318 moe430aPROSITE found 8922 I also downloaded and installed the 1.12.0 versions of moe430b, rae230a, rae230b, hgu133a and hgu133plus2, and those all seemed to work fine on my computer.
