split.by error in Clustered_DotPlot function

[apal6]

Hi,

Thank you for the package. I was able to use the function Clustered_DotPlot without using split.by parameter. I want to look at the expression at different timepoints and time2 column is there in my metadata but i get an error when I try to use split.by.

`Clustered_DotPlot(seurat_object = _Seurat, split.by = "time2", features = c("gene1"),

•               colors_use_exp = PurpleAndYellow())
  

Error in [.data.frame(percent_mat, , idx) : undefined columns selected`

Could you help?

Thank you!

Hi,

Are you only providing one gene to the function to plot? Could you paste the output of traceback() after the error occurs?

Thanks, Sam

Hi @apal6,

Just wanted to followup on my previous message to try and figure out the issue.

Hi @samuel-marsh,

Thank you for following up. No, I using multiple genes. Here is the output of traceback()

Hi @apal6,

Sorry for delay getting back to you. Before we continue trying to troubleshoot back and forth I wanted to check if it is possible to share the object so I can try and troubleshoot directly? If so please send me an email: [email protected] and I will send you google drive link to upload the object.

If not let me know here and there are couple of things we can try back and forth here.

Best, Sam

Hi @samuel-marsh ,

I think I got it working. Thank you for your time.
