Error when running quantifySplicing

[jlbuerer]

Hi when I run the following script:

library(psichomics)

wd <- '/users/jbuerer/scratch/alternative_splicing_bps'
setwd(wd)

download_folder <- file.path(wd, 'data')

gtex_data <- loadGtexData(download_folder, data = 'junctionQuant', release = 10)
 
gtex_junctions <- gtex_data$GTEx_V10$`Junction quantification`

splicing_anno <- loadAnnotation('AH63657')

splicing_quant <- quantifySplicing(splicing_anno, gtex_junctions)

I get the following error:

Error in class(eventData) <- c("eventData", class(eventData)) : 
  attempt to set an attribute on NULL
Calls: quantifySplicing
Execution halted

Do you have any insight into why this might be? Thanks
