Error in !isSpike(object) : invalid argument type

[yicheinchang]

Hi,

I guess this is somehow related with #53 or 10X data. I tried to run sc3 on a 10x data set. Based on #53 , I manually convert both counts slot and logcounts slot to a standard/regular matrix. However, I am getting another error

Setting SC3 parameters...
Error in !isSpike(object) : invalid argument type

It seems the issue came from gene_filter. Set gene_filter = FALSE will make the code work. 10X data most likely will have no Spike-in. For my data set, isSpike(mySingleCellExperiment) will return NULL, which is the expected behavior.

Here is my session info:

@yicheinchang sorry for a delayed response, have you figured the problem? If not, could you please share your dataset with vk6@sanger.ac.uk?

[yicheinchang]

Hi @wikiselev Unfortunately, I couldn't share my actual data. However, I suspected this is a 10X specific issue. Perhaps you can reproduce this issue by using the public datasets released by 10X Single Cell Gene Expression Datasets

In addition, I found a quick workaround. All you need is to explicitly set the spike-in information even when there is no spike-in in the experiment. For example,

isSpike(sce, "ERCC") <- rep(FALSE, time = nrow(sce))

Best, Yi-Chien.
