Good afternoon,

 

I am trying to access this dataset from cBioPortal: Metastatic Breast Cancer: 2013-2016 (DFCI, CCR 2020)

 

Synapse team told me to ask you directly.

 

Do you think you could help me by any chance?

 

Thank you

 

Best

Hi Guillaume,

You can access the dataset through the public GENIE portal:https://genie.cbioportal.org/

Thanks,

Hi Ritika,

 

I do not see how to download the dataset on cbioportal. Could you help me to fix it?

It is indicated that we can have access via Synapse, but the synapse team told me to ask you directly as I do not see it on their website.

 

Thank you

Guillaume

Hi Ritika,

 

I hope you’re doing well.

 

I wanted to follow up regarding access to the Metastatic Breast Cancer (MBC GENIE 2020) dataset. I’m still having trouble downloading it via cBioPortal. As mentioned previously, Synapse indicated that I should reach out to you directly, but I’m not seeing the dataset available on the platform.

 

Could you please advise on how to access or download the data?

 

Thank you very much for your help.

 

Best regards,

Guillaume

Hi Guillaume,

Apologies for the delay.
For the clinical data, you can download it through the widget on the top right corner of the portal.
For the genomic data, you can download the GENIE data from Synapse: https://www.synapse.org/Synapse:syn7222066/wiki/410924 and then subset for the samples in the cohort.

Thanks,
Ritika
