Combined Cohorts

Hachem Ziadeh

Hello,

I have 2 different sets of cohorts that were already created by combining other cohorts together.

I want to use  substraction for these 2 cohorts in order to create a new cohort. When I try to do it,  it says that a combined cohort cannot be combined a second time.

Any alternative method to achieve this substraction?

-Thank you

    Hello Hachem,

    I think this is a limitation of the cohort browser. To combine the two cohorts, I recommend using JupyterLab, where you can apply the specific join method needed. Both Python and R are supported within this environment, allowing you to perform your analysis. For helpful resources to get started with data analysis, you can refer to the UK Biobank GitHub repository, which contains useful guides and example code.

    Thank you for using the forum,

    Harvey
