Error with the demo in R

[Carmen Ortega Santos]

Hey all,

I am running the demo for MaAslin2 on R. However, I keep getting the following error after running the following code:

fit_data <- Maaslin2(input_data, input_metadata, 'demo_output', transform = "AST", fixed_effects = c('diagnosis','dysbiosisnonIBD','dysbiosisUC','dysbiosisCD','antibiotics','age'), random_effects = c('site','subject'), standardize = FALSE)

ERROR that shows up on the console:

Error in data.table::fread(input_data, header = TRUE, sep = "\t") : 

  Input is empty or only contains BOM or terminal control characters

Does anyone come across the same error when trying the demo?

Any suggestions or comments are appreciated.

Carmen
