Chromosomes attribute missing

[cmdoret]

Hello,

I tried running HiCDOC on my samples, as explained in the readme. HiCDOCDataSetFromCool runs successfully, however I obtain the following error when running filterSmallChromosomes:

Error in eval_tidy(xs[[j]], mask) : 
  no slot of name "chromosomes" for this object of class "HiCDOCDataSet"
Calls: filterSmallChromosomes ... %>% -> eval -> eval -> tibble -> tibble_quos -> eval_tidy
Execution halted

If I skip filterSmallChromosomes and run filterWeakPositions directly, I get the same error:

Error in eval_tidy(xs[[j]], mask) : 
  no slot of name "chromosomes" for this object of class "HiCDOCDataSet"
Calls: filterWeakPositions ... %>% -> eval -> eval -> tibble -> tibble_quos -> eval_tidy

Inspecting the structure of the HiCDOCDataSet object reveals a chromosome attribute, instead of chromosomes. Could that be the issue (the missing s) ?

I figured my issue; I made a mistake and used a HiCDOCDataSet object instead of HiCDOCExp !
