Warning for samples.tsv column names already defined in the standard.

[achilleasNP]

Hi,

I get the warning below while all three columns mentioned are a required part of the standard. I get the warning, even when I use the v1.7.0 schema (using the -s v1.7.0) that includes the definition of those columns.

  2: [WARN] Tabular file contains custom columns not described in a data dictionary (code: 82 - CUSTOM_COLUMN_WITHOUT_DESCRIPTION) 
	./samples.tsv 			
       Evidence: Columns: sample_id, participant_id, sample_type not defined, please define in: /samples.json 

I am using version 1.14.4 of the validator.

Thanks in advance,
Achilleas
