Hello Peters,

I have used package called DMRcate to  analyse 450k data. I want to find the gene which associates the DMRs.And I met some questions.The outputs include gene_assoc, group, hg19coord, no.probes, minpval, meanpval and maxbetafc,when  I used the old version to analyse 450k data.

But when I update the package,the outputs became coord, no.cpgs, minfdr, Stouffer, maxbetafc,meanbetafc.There is no result  of "gene_assoc".I want to find the gene names associating "coord",can you help me ? Can you please tel me how to associate the gene by using the newest DMRcate packages.

 

There follow the output results of the newest DMRcate.

There follow the output results of the older DMRcate.

Thank you !

The extractRanges() function now appends promoter associations from Gencode/Ensembl instead. I find this annotation more reliable than Illumina's. Have a look at page 4 of the vignette:

Tim,

Thanks for your reply.And now I meet a new question.I can not load the DMRcate package.

There follows the error.

Loading required package: splines
Loading required package: DMRcatedata
Error: package or namespace load failed for 'DMRcate' in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/data/users/robots/software/R_Bioconductor/R_Bioconductor-3.4.2/lib64/R/library/VariantAnnotation/libs/VariantAnnotation.so':
  /lib64/libz.so.1: version `ZLIB_1.2.3.3' not found (required by /data/users/robots/software/R_Bioconductor/R_Bioconductor-3.4.2/lib64/R/library/VariantAnnotation/libs/VariantAnnotation.so)

Can you give me some advise?

Thank you!

This is a problem with your version of zlib, not DMRcate. Looks like you need to update the version of zlib on your machine. This thread may be of help: https://www.biostars.org/p/89217/

Cheers,

Tim
