Indeed, the version of `xcms` that you are using is too old. Version `3.12.0` does not yet support to return MS2 data as a `Spectra`. You have 2 options: 1)...

I guess that package `msdata` is not intalled. You can check that with `library("msdata")`, if that throws an error you should install it with `BiocManager::install("msdata")`

Hi Ting, sorry for the late reply. in order to run the tutorial you would need to have [docker](https://hub.docker.com/editions/community/docker-ce-desktop-windows) installed. Then, in the Windows cmd prompt you would need to...

I have two updates: firstly, I've now created also an SQLite version of the MassBank data for the use with the `MsBackendMassbankSql`. You can download that database file from [here](https://github.com/jorainer/SpectraTutorials/releases/tag/2021.03),...

@tsufz , that would be great! The only problem is that the tables needed for `MsBackendMassbankSql` are actually only `VIEW`s in the MySQL database, not real tables. I've tried to...

I'm quite confident that it is safe to ignore this error. The `x$.self$finalize()` function is called just before the object is removed (by the garbage collector, I believe). At this...

I keep the issue however open to remind me to dig into this once I have more time.

Yes, I know. Didn't have the time to look into this. While it is annoying to have these errors popping up randomly, you can savely ignore them.

I suspect this is all related to some garbage collection related things going on in R (see also issue #305). @luckygoh , can you reproduce the error, i.e. if you...

Interesting - so it is most likely related to `mzR` then, because I guess `metaboanalyst` is not using code from `xcms`...
