error, unable to find an inherited method for function '.readSampleId' for signature

I could not reproduce this error. If it persists after restarting your R session, could you please share sessionInfo()?

[wcmoors]

was there a solution to this?

[smgogarten]

Restart your R session. If that doesn't work and you are seeing this error, please share sessionInfo().

Hello, Thank you asking it again. I could resolve this error. It was coming from the old version R. I tried to do genesis under R 3.5.1. After installing the packages under 3.6.0, I could run genesis without errors. Best, Jaeyoon From: Stephanie M.

Hate to dredge this up again, but I'm getting the same error. Here's my sessionInfo()

Edit to add that I have restarted R and encounter the same issue.

I think this is an error that can be resolved by restarting R. Can you try starting a brand-new R session and running the following?

library(GENESIS)
library(SNPRelate)

gdsfile <- system.file("extdata", "HapMap_ASW_MXL_geno.gds", package="GENESIS")
gds <- snpgdsOpen(gdsfile)
class(gds) # should see "SNPGDSFileClass"

data("HapMap_ASW_MXL_KINGmat")
mypcair <- pcair(gds, kinobj = HapMap_ASW_MXL_KINGmat, divobj = HapMap_ASW_MXL_KINGmat)

snpgdsClose(gds)

Hello, I am having the same issue but this time with pcrelate. I am wondering if the R version or the version of the packages could be the issue?

I have run the above code in a new R session, but with pc relate at the end (like below) but pcrelate still generates the error, any thoughts?

Code that is sufficient to produce error, R v 4.1.3 :

library(GENESIS)
library(SNPRelate)

gdsfile <- system.file("extdata", "HapMap_ASW_MXL_geno.gds", package="GENESIS")
gds <- snpgdsOpen(gdsfile)
class(gds) # should see "SNPGDSFileClass"

data("HapMap_ASW_MXL_KINGmat")
mypcair <- pcair(gds, kinobj = HapMap_ASW_MXL_KINGmat, divobj = HapMap_ASW_MXL_KINGmat)

mypcrelate <- pcrelate(gds, pcs = mypcair$vectors[,1:2],
training.set = mypcair$unrels,
BPPARAM = BiocParallel::SerialParam())
snpgdsClose(gds)

[AlexHatoum]

I have figured out the issue. It is with the way the .gds files are read into R, perhaps in different versions. If your data produces this error, reading the .gds files back into R in different ways can help (which you should probably do after restarting R according to this thread, but in my experience it is not necessary as long as you can reload in the .gds files). It is always best to do so using the two part commands like this:

HapMap_geno <- GdsGenotypeReader(filename = "MyGDS.gds")
HapMap_genoData <- GenotypeData(HapMap_geno)

Instead of using other GDS commands like this:
genofile <- snpgdsOpen("MyGDS.gds")

Both sets of code produce the same class of object but the package throws an error for the latter and not the former. Apologies to the developers if this is something obvious, but I thought I would just post here in case others run into this issue.

Best,

Alexander

@AlexHatoum pcair has more options for input classes than pcrelate, which is why you saw the error for the latter but not the former. This has to do with the way the two functions are implemented internally: pcair calls the snpgdsPCA function in the SNPRelate package, so it can accept SNPRelate classes, but pcrelate requires an Iterator object defined in GWASTools or SeqVarTools. You can see this difference in the "Usage" section of the man pages for the two functions:

Usage:

     ## S4 method for signature 'gds.class'
     pcair(gdsobj, kinobj = NULL, divobj = NULL,
 <...>
     ## S4 method for signature 'SNPGDSFileClass'
     pcair(gdsobj, ...)
     ## S4 method for signature 'GdsGenotypeReader'
     pcair(gdsobj, ...)
     ## S4 method for signature 'MatrixGenotypeReader'
     pcair(gdsobj, ...)
     ## S4 method for signature 'GenotypeData'
     pcair(gdsobj, ...)
     ## S4 method for signature 'SeqVarGDSClass'
     pcair(gdsobj, ...)
     

vs

Usage:

     ## S4 method for signature 'GenotypeIterator'
     pcrelate(gdsobj,
<...>
     ## S4 method for signature 'SeqVarIterator'
     pcrelate(gdsobj,
