Patient clinical attributes not shown in all patient samples

[oplantalech]

As you can see in the screenshot for study lgg_ucsf_2014 in cbioportal.org, patient attributes like "Gender" are only displayed in one of the samples of the patient, but not in all:

I think gender is a patient attribute. I don't see it on the patient view for the samples. @zhx828 do you know why it shows up this way?

Is there some logic on the frontend that assigns the gender to one sample?

[zhx828]

@inodb the patterns looks like only the first sample got the gender info. Yeah, the clinical table will map all patient clinical data to sample level. I can take a look at the issue.

@zhx828 I was running into errors when there is only one sample in the study. My fix in cBioPortal/iViz#739 even fixes this

@kalletlak I doubt it will because the logic of mapping P to S data is in cbioportal, separated out from iviz project. Let me take a look.

@kalletlak looks good. It does solve the issue. I will send the pull request to portal.
