Trouble shooting

'This workbook is currently referenced by another workbook and cannot be closed' when I use VBAObjectManager

  1. uninstall AT & CGHTools
  2. use privilege manager to run installer
  3. use privilege manager to open excel and run VBAObjectManager

Another canonical method is

  1. Ctrl + F11 to open VBE
  2. click Project > ArrayTools. Click Tools > Reference. Make sure CGHTools is not checked.
  3. Click Project > CGHTools. Click Tools > Reference. Make sure ArrayTools is checked.

Registrition

Check update error

BRB-ArrayTools was not able to check for software updates. The server may be down or too slow right now or you may not connect to the internet.

Solution: Check LatestVersion.txt file on server. When we download the file using wget on Windows, the content becomes one line. Better to change the format when it was uploaded from PC or manually copy the text in linux environment.

The source code is in Utilities:CheckForPath(). 

msiShellAndWait Chr(34) & RscriptExe & Chr(34) & " -e " & Chr(34) & "download.file('http://linus.nci.nih.gov/new_updates/ArrayTools_LatestVersion.txt', '" & GetArrayToolsDir("/") & "/updates/ArrayTools_LatestVersion.txt', mode='wb')" & Chr(34), False

That is 

C:\\PROGRA~1\\R\\R-32~1.4\\bin\\Rscript.exe" -e "download.file('http://linus.nci.nih.gov/new_updates/ArrayTools_LatestVersion.txt', 'C:/Program Files (x86)/ArrayTools/updates/ArrayTools_LatestVersion.txt', mode='wb')

To see the format is DOS format (CRLF terminator or \r\n) or UNIX format (\n), we can use file command (the output will be different)

C:\ArrayTools\Updates\ArrayTools_CurrentVersion.txt: Non-ISO extended-ASCII English text, with CRLF line terminators

How to Test

  • Test when internet is not available. For example, GO analysis requires downloading GO.db package. BugReport.tar.gz will be generated if there is a problem with GO.db installation.
  • Test special characters (# sign) in the experiment descriptor worksheet. A wrong <ExpDescWkSht> file used by the DHV (dynamic heatmap viewer) was generated. The reason is read.table() forgot to use comment.char() argument. See bugreportDessen project. PS the error was caught in RserveVBA.
  • Test column header contains double quotes (eg: my "GWAS" score). Some analyses like quantitative trait analysis will fail.
  • Test the case gene annotation was not done so gene symbols were not available. (miRNA project) This causes a bug in the class comparison -> IPA output. The GeneID file may miss some gene identifiers. See PreparegGeneHTMLtable.R.
  • Test the case Symbol was used in the first column of gene identifier file. This will result in two 'Symbol' column in Gene annotations worksheet and break the the code in CreateIPAOutput().
  • Extreme number of arrays (eg 3, 10) This is used to test chunking, ...
  • Extreme number of genes.
  • Use non-default options.
  • Analyze one project after another project to see if there is any memory issue.
  • Use unreasonable entry like 1.5 if the value should be less than or equal to 1.
  • Use long path name for project which causes an error when Fortran program was being launched. The wikipedia page said there is a 126 characters limit in interactive mode.
  • Test on fresh machine (no R libraries installed).
  • Data with lots of missing values.
  • Test on a subset of arrays only.
  • Run an analysis when we don't expect the data type fits in (eg RNA-Seq analysis on regular microarray data).

Windows Virtual Machine

  • Download Windows 10 iso from Microsoft (no log in is required)
  • Use MS Office 2007

Misc

Conversion of an old project

  • For an old project needs to be converted, the old project folder will be backed up with a new name 'XXXX_ArrayToolsOldProject'.

After running the class comparison

Filtered log ratio worksheet

Arrays in 'filtered log ratio worksheet' will be sorted based on the class variable (still keeping empty arrays). For example, if we select 'BRCA1 V BRCA2' column, arrays will be sorted by BRCA1, BRCA2 and empty. If we select 'BRCA1 v Sporadic', arrays will be sorted by BRCA1, empty and Sporadic. The gene expression value Html page is also sorted by the class variable (excluding empty label arrays).

Clustered heatmap of significantly expressed genes

Note that the color legend says 'Centered log ratio' (dual channel) or 'Scaled and centered value' (single channel). What 'centered' means is it will center gene expression across arrays for each.

VBA source code

  • AddCustomMenu() in CustomMenu.bas - the main menu starts here.
  • You can step the code by using keyboard shortcuts
    • F5: continue
    • F8: step in
    • Shift + F8: step over
    • Ctrl + F8: go to the cursor

Annotate the data

  • Consider the Affymetrix first.
  • Search "Annotate the data" in <CustomMenu.bas>. It shows if users have click "Import Affymetrix annotations", it will trigger the function "ShowAffymetrixDownload" which is located in "AffyDialog" module.
  • Set a break at some line in ShowAffymetrixDownload function
  • At the end you will see it calls the form fmDownloadAffyFile.Show() to display the download affymetrix dialog. Once the command button is clicked, the process goes to the subroutine CommandButtonImport_Click() in the form.
  • Eventually it will execute InsertGeneAnnotationSheet AnnotateFromMenu:=True. Press F8 to go into this function. We can see the function InsertGeneAnnotationSheet is defined in Annotation.bas. Note that there are 4 similar functions defined in Annotation.bas.
    • InsertGeneAnnotationSheet
    • InsertGeneAnnotationSheet_lumi
    • InsertGeneAnnotationSheet_lumiMethy
    • InsertGeneAnnotationSheet_Bioc
  • In Annotation.bas, it executes MatchProbeSetsOK = MatchProbeSets(ChipType).
  • The VBA MatchProbSets function executes a series of R commands. The most important one is the following
RRunSuccess "ReturnMsg <- MatchAffyAnnotation(ChipName, ProjectPath, UniqueIdHeader, ShowProgress=T)", , True
  • In fact, we can see what exact R function (located in <BiocUtil.R>) is called in each VBA function (located in <Annotations.bas>).
    • InsertGeneAnnotationSheet -> MatchProbeSets(ChipType) -> MatchAffyAnnotation(ChipName, QueryIdHeader)
    • InsertGeneAnnotationSheet_lumi -> MatchNuID(annopkg) -> MatchlumiAnnotation(anno, UniqueIdHeader)
    • InsertGeneAnnotationSheet_lumiMethy -> MatchTargetID(annopkg) -> MatchlumiMethyAnnotation(anno, UniqueIdHeader) or MatchMethy450kAnnotation(anno, UniqueIdHeader)
    • InsertGeneAnnotationSheet_Bioc -> MatchQueryID(Species, QueryIdHeader) -> MatchBiocAnnotation(annoPkg, QueryIdHeader)

DataRMatrix<-matrix(readBin(con="C:/ArrayTools/Sample datasets/Perou/Perou -Project/BinaryData/GreenRaw1", 
                    what="numeric", n=2998*3, size=4), nr=2998, byrow=F) 
# check <Import.txt> to find number of genes and chunks

Good R writing habit

  • Use indentation.
  • Use parenthesis if needed. For example, the following is bad
if (something) DoSomething
else DoAnother
  • read.delim() is better than read.table(). When we use read.table() or write.table(), use their options to avoid special characters woes. Note: quote=FALSE in write.table() does not give a correct result as we expect, so use quote="" specifically.
read.table(FILENAME, stringAsFactors=FALSE, header=TRUE, sep="\t",
           na.strings=c('NA',''), fill=TRUE, comment.char='', quote="")
write.table(FILENAME, row.names=FALSE, col.names=TRUE, sep="\t", quote="")
