Hello
I've being trying to get charm to read in some Nimblegen array data
that I had to convert from PAIR to XYS, also making an annotation
file.
All goes swimmingly, until I try to use readCharm, although the data
appears to load, I get the following error when using readCharm:
The following columns in sampleKey contain discrepant values between
channels and are being removed: 1
It's not clear what this means, as I have looked at the two channel
files (532 and 635) and the structure is essentially the same.
Subsequent analyses fail, I assume because of missing data.
If I look at my loaded dataset with rawData I get the following:
> rawData
TilingFeatureSet (storageMode: lockedEnvironment)
assayData: 389307 features, 39 samples
element names: channel1, channel2
protocolData
rowNames: N3 N9 ... E2 (39 total)
varLabels: filenamesChannel1 filenamesChannel2 dates1 dates2
varMetadata: labelDescription channel
phenoData
rowNames: N3 N9 ... E2 (39 total)
varLabels: sampleID tissue arrayUT arrayMD
varMetadata: labelDescription channel
featureData: none
experimentData: use 'experimentData(object)'
Annotation: pd.2006.11.02.hg18.cpg.promo
Can anyone help?

Hey,
What's actual code you are running? It looks like you read the data in
with
readCharm:
rawData = readCharm(...)
So is that discrepancy just a warning, and not an error?
Also, if you are using a methyl-enrichment protocol (like MeDip) with
the
charm package, you need to reverse the inputs - charm assumes McrBC
which
enriches for unmethyled DNA, so the "treatment" input here would be
the
reverse. That might be one reason why downstream analyses are failing.
Could you provide more code of exactly what fails later?
Thanks,
Andrew Jaffe

Hi,
Thanks for your help
I have solved the first part of the puzzle, it was due to incorrect
conversion of the PAIR to XYS files. The other problems are
1) I get the following error when trying to do QC:
> pmq= pmQuality(rawData)
Error in tapply(x[bgIndex, i], bgNgc, ecdf) : subscript out of bounds
2) I thought I had this fixed, and then got this as well when I
tried to identify unmethylated control probes:
> ctrlIdx <- getControlIndex(rawData, subject=Hsapiens,
noCpGWindow=60)
Error in sqliteExecStatement(con, statement, bind.data) :
RS-DBI driver: (error in statement: no such column: chrom)
I am using MeDIP as it happens, so I need to reverse the 532 and 635
inputs do you think? 532 is labelled as INPUT in the samplekey.txt and
635 is MBD.
Thanks
Andrew

PS I have reversed the inputs, and that looks a lot better.
However it still fails on point 2.
I am using the BSgenome.Hsapiens.UCSC.hg18 library - do you think that
has anything to do with it?

Try running the code inside getControlIndex and see where it fails.
Also, "The following columns in sampleKey contain discrepant values
between
channels and are being removed: 1" is not an error and is not even a
warning, it's just a message. The function takes a sampleKey data
frame
with 2 rows per sample and returns one (phenoData) with 1 row per
sample,
so columns with different values in the 2 rows for the same sample
can't be
included in that output data frame. You'll always get this message
for the
file name column since one row has .532 and the other has .635.

Hi
It fails at the following line:
chr <- pmChr(dat)
And gives the error:
Error in sqliteExecStatement(con, statement, bind.data) :
RS-DBI driver: (error in statement: no such column: chrom)

Try running the code inside getControlIndex and see where it fails.
Also, "The following columns in sampleKey contain discrepant values
between channels and are being removed: 1" is not an error and is not
even a warning, it's just a message. The function takes a sampleKey
data frame with 2 rows per sample and returns one (phenoData) with 1
row per sample, so columns with different values in the 2 rows for the
same sample can't be included in that output data frame. You'll
always get this message for the file name column since one row has
.532 and the other has .635.

Hi,
Thanks for your help
I have solved the first part of the puzzle, it was due to incorrect
conversion of the PAIR to XYS files. The other problems are
1) I get the following error when trying to do QC:
> pmq= pmQuality(rawData)
Error in tapply(x[bgIndex, i], bgNgc, ecdf) : subscript out of bounds
2) I thought I had this fixed, and then got this as well when I
tried to identify unmethylated control probes:
> ctrlIdx <- getControlIndex(rawData, subject=Hsapiens,
noCpGWindow=60)
Error in sqliteExecStatement(con, statement, bind.data) :
RS-DBI driver: (error in statement: no such column: chrom)
I am using MeDIP as it happens, so I need to reverse the 532 and 635
inputs do you think? 532 is labelled as INPUT in the samplekey.txt and
635 is MBD.
Thanks
Andrew

Hey,
What's actual code you are running? It looks like you read the data in
with readCharm:
rawData = readCharm(...)
So is that discrepancy just a warning, and not an error?
Also, if you are using a methyl-enrichment protocol (like MeDip) with
the charm package, you need to reverse the inputs - charm assumes
McrBC which enriches for unmethyled DNA, so the "treatment" input here
would be the reverse. That might be one reason why downstream analyses
are failing. Could you provide more code of exactly what fails later?
Thanks,
Andrew Jaffe

Hello
I've being trying to get charm to read in some Nimblegen array data
that I had to convert from PAIR to XYS, also making an annotation
file.
All goes swimmingly, until I try to use readCharm, although the data
appears to load, I get the following error when using readCharm:
The following columns in sampleKey contain discrepant values between
channels and are being removed: 1
It's not clear what this means, as I have looked at the two channel
files (532 and 635) and the structure is essentially the same.
Subsequent analyses fail, I assume because of missing data.
If I look at my loaded dataset with rawData I get the following:
> rawData
TilingFeatureSet (storageMode: lockedEnvironment)
assayData: 389307 features, 39 samples
element names: channel1, channel2
protocolData
rowNames: N3 N9 ... E2 (39 total)
varLabels: filenamesChannel1 filenamesChannel2 dates1 dates2
varMetadata: labelDescription channel
phenoData
rowNames: N3 N9 ... E2 (39 total)
varLabels: sampleID tissue arrayUT arrayMD
varMetadata: labelDescription channel
featureData: none
experimentData: use 'experimentData(object)'
Annotation: pd.2006.11.02.hg18.cpg.promo
Can anyone help?

pmChr is a function in the oligo package, not the charm package.
Apparently your dat is not a valid TilingFeatureSet object.
If you look your error message and at the definition of pmChr--type
selectMethod(pmChr,"TilingFeatureSet")--you can see that the problem
seems
to be that your dat object has no "chrom" column in its featureSet
table.
To see this type
dbGetQuery(db(dat),"SELECT * from featureSet")
There should be a column named "chrom" with values for each probe like
"chr10", "chrX", etc.
Maybe if you study the oligo package (and maybe DBI package) more you
can
figure out how to make your dat object valid.

More importantly, how was the respective pd* (annoation) package
created?
Was the NDF modified in any way? If so, how?

Hi
I get the following:
> head(dbGetQuery(db(rawData),"SELECT * from featureSet"))
# fsetid man_fsetid
1 6 chr10:100017797-100018797
2 7 chr10:100164731-100165731
3 8 chr10:100196494-100197494
4 9 chr10:100217275-100217975
5 10 chr10:100982061-100982762
6 11 chr10:100983644-100984344
Obviously the column ID is wrong, but I used the pdInfoBuilder package
to create it as per the vignette, with the NDF unmodified. I obviously
had to convert the PAIR files from the CD to XYS files, but did this
as per posts on the bioconductor mailing lists.
Thanks for all the help so far
Andrew

pmChr is a function in the oligo package, not the charm package.
Apparently your dat is not a valid TilingFeatureSet object.
If you look your error message and at the definition of pmChr--type
selectMethod(pmChr,"TilingFeatureSet")--you can see that the problem
seems
to be that your dat object has no "chrom" column in its featureSet
table.
To see this type
dbGetQuery(db(dat),"SELECT * from featureSet")
There should be a column named "chrom" with values for each probe like
"chr10", "chrX", etc.
Maybe if you study the oligo package (and maybe DBI package) more you
can
figure out how to make your dat object valid.

Can you share the exact code used to create the pd package? I
apologise,
but to understand what is going on, I need to recreate precisely the
scenario you describe. The package is expected to be created with 3
items:
NDF, POS and XYS files....
thanks,

Apparently your dat is not a valid TilingFeatureSet object.
If you look your error message and at the definition of pmChr--type
selectMethod(pmChr,"TilingFeatureSet")--you can see that the problem
seems
to be that your dat object has no "chrom" column in its featureSet
table.
To see this type
dbGetQuery(db(dat),"SELECT * from featureSet")
There should be a column named "chrom" with values for each probe like
"chr10", "chrX", etc.
Maybe if you study the oligo package (and maybe DBI package) more you
can
figure out how to make your dat object valid.

Hello
I solved the problems. In essence, the PAIR files I had been given
were supplied without control probes in the PAIR files. Adding these
locations in with a script from the NDF file (and NA) whilst
converting the PAIR files now means it works perfectly!
Many thanks

Hi Andrew,
One of the things readCharm does is match up the two channel files
(_532 and _635) for each sample. The input to readCharm is file-
centric (i.e. two files per sample), and the output is sample-centric.
When annotating samples it tries to keep as many columns of the sample
description file (sampleKey) you give it as possible. A requirement
for this is that the values in a given column must be identical for a
given green channel file and its matching red channel file. The
warning ("The following columns in sampleKey contain discrepant values
between channels and are being removed") means that this is not the
case. You could take a look in column 1 and see if there is a
discrepancy for one or more samples. (If you don't care to keep the
information in column 1 you can safely ignore the warning.)
Best,
Martin

Subsequent analyses fail, I assume because of missing data.
