# Adding a sample

![](/files/K4mA6UNtjMw6ef2gH7hg)

You can choose one of the following options:

* **Existing sample**: Pick one of the samples already loaded on the platform
* **Upload new sample**: Upload files from your PC and enter sample name
* **Choose from storage**: Choose files from your cloud storage and enter sample name
* **No sample**: Postpone uploading files but proceed with case creation or skip uploading files for family members other than Proband

{% hint style="warning" %}

* The Add New Case flow does not validate that sample IDs are unique or that input files are uncorrupted. Please ensure sample IDs are unique and that input files are valid before creating the case.
* A case won't run if Proband sample files are missing. However, sample files are not mandatory for the rest of the family members (although highly recommended).
* When choosing an existing file path, the samples used may be cached from the original run. For a top-up flow please use a new file path.
* When you are loading sample files from your PC or choosing them from the storage, and there is more than one file per sample, please ensure that **all** the necessary files are simultaneously selected in the upload pop-up. You may only select one file type per case (i.e. you may not select both a .vcf and a .bam at the same time).
