Hi there,

I'm trying to import a "loom" file with the devel version and I'm getting an error:

>library(LoomExperiment)

> scle <- LoomExperiment::import("l5_all.agg.loom", type="SingleCellLoomExperiment")
Error in normalizeDoubleBracketSubscript(i, x, exact = exact, allow.NA = TRUE,  : 
  invalid [[ subscript type: NULL

This same command works perfectly with R version 3.6.

Does anyone have any clue? Thanks

This looks like a version mis-match error; can you confirm BiocManager::valid() returns TRUE? Can you also report, immediately after the error, the result of traceback()? And finally, can you make your example reproducible by using the loom file distributed with the package

fl = system.file(package="LoomExperiment", "extdata", "L1_DRG_20_example.loom")
LoomExperiment::import(fl, type = "SingleCellLoomExperiment")

or some other publicly available loom file?

Thanks Martin,

Yes, the result of BiocManager::valid() is TRUE.

The result of traceback() is:

> traceback()
16: stop("invalid [[ subscript type: ", subscript_type)
15: normalizeDoubleBracketSubscript(i, x, exact = exact, allow.NA = TRUE, 
        allow.nomatch = TRUE)
14: getListElement(x@listData, i, exact = exact)
13: getListElement(x@listData, i, exact = exact)
12: getListElement(x, i, ...)
11: getListElement(x, i, ...)
10: .nextMethod(x = x, i = i)
9: callNextMethod()
8: df[[rowname]]
7: df[[rowname]]
6: .importLoom_DataFrame(con, "/col_attrs", colnames_attr, unlist(metadata[reducedDims_names]))
5: .local(con, ...)
4: import(FileForFormat(con), ...)
3: import(FileForFormat(con), ...)
2: LoomExperiment::import("l5_all.agg.loom", type = "SingleCellLoomExperiment")
1: LoomExperiment::import("l5_all.agg.loom", type = "SingleCellLoomExperiment")

Also, I am able to import the example loom file:

> fl = system.file(package="LoomExperiment", "extdata", "L1_DRG_20_example.loom")
> LoomExperiment::import(fl, type = "SingleCellLoomExperiment")
class: SingleCellLoomExperiment

colData names(103): Age AnalysisPool ... cDNA_Lib_Ok ngperul_cDNA
reducedDimNames(0):
altExpNames(0):
rowGraphs(0): NULL
colGraphs(2): KNN MKNN

So, the problem is with the data I downloaded from http://mousebrain.org/, then?

Many thanks

To me it looks like another bug in LoomExperiment. The data comes from https://storage.googleapis.com/linnarsson-lab-loom/l5_all.agg.loom and is easily reproducible

url = "https://storage.googleapis.com/linnarsson-lab-loom/l5_all.agg.loom"
path = BiocFileCache::bfcrpath(rnames = url)
LoomExperiment::import(path)

with

> LoomExperiment::import(path)
Error in normalizeDoubleBracketSubscript(i, x, exact = exact, allow.NA = TRUE,  :
  invalid [[ subscript type: NULL

Thanks for the additional information (the source of the data) to make this reproducible. I'll direct the appropriate person to this (and your other issue)

I opened an issue https://github.com/Bioconductor/LoomExperiment/issues/13 and did some initial debugging; I'm not sure Marcel why it does not fail for you?

I had the fix already applied in my system without knowing it. There is a pending PR here: https://github.com/Bioconductor/LoomExperiment/pull/12

After reinstalling from BiocManager, I get the same error:

> url <- "https://storage.googleapis.com/linnarsson-lab-loom/l5_all.agg.loom"
> path <- BiocFileCache::bfcrpath(rnames = url)
> LoomExperiment::import(path)

This is fixed in version 1.5.3, which will be available in the 'devel' branch in 48 hours and in the the new Bioconductor release later in the week.
