Data Loading : What You Need To Change

This page contains an overview to help you transition to the new file formats. As this should be a one-time operation for all users, this page is only temporary.

1. Update your genes table, see issues #799 and #805 on how to do this
   • Reason: cBioPortal in the past accidentally imported the wrong column as HUGO symbol. This will cause many errors during the validation process.
2. Check the following table for your data types:

DataType	What you have to do
Cancer Study	(optionally) Add add_global_case_list
Cancer Type	Create the meta file
Discrete Copy Number Data	Update meta file: change stable_id to gistic, cna, cna_rae or cna_consensus add data_filename Remark: copynumber profiles used by the cross-cancer histogram no longer use the name to check whether the data is GISTIC or RAE; this is now based on the stable_id.
Copy Number Data	Update meta file: if datatype is LOG-VALUE change it to LOG2-VALUE if datatype is CONTINUOUS, change stable_id to linear_CNA add data_filename
Segmented Data	Update meta file: change genetic_alteration_type to COPY_NUMBER_ALTERATION change datatype to SEG remove: stable_id, show_profile_in_analysis_tab, profile_name, profile_description add: description, data_filename
Expression Data	Update meta file: check your stable_id against the table add data_filename
Mutation Data	Update meta file: change your stable id to mutations add data_filename
Fusion Data (TODO)	Update meta file: add data_filename
Methylation Data	Update meta file: change stable_id to methylation_hm27 or methylation_hm450 add data_filename
RPPA Data	Update meta file: change genetic_alteration_type to PROTEIN_LEVEL change datatype to LOG2_VALUE or Z-SCORE change stable_id to rppa or rppa_Zscores add data_filename
Clinical Data	Create two separate meta files, one for samples and one for patients Create two separate data files, one for samples and one for patients remove the row describing whether an attribute is a SAMPLE or a PATIENT attribute For full instructions, check the file formats
Case Lists	-
Timeline Data	Update meta file(s): remove: stable_id, show_profile_in_analysis_tab, profile_name, profile_description add: data_filename
Gistic Data	Create the meta file
MutSig Data	Create the meta file
