# POST /sequencestore/{sequenceStoreId}/upload

`POST /sequencestore/{sequenceStoreId}/upload`

Initiates a multipart read set upload for uploading partitioned source files into a sequence store. You can directly import source files from an EC2 instance and other local compute, or from an S3 bucket. To separate these source files into parts, use the `split` operation. Each part cannot be larger than 100 MB. If the operation is successful, it provides an `uploadId` which is required by the `UploadReadSetPart` API operation to upload parts into a sequence store.

To continue uploading a multipart read set into your sequence store, you must use the `UploadReadSetPart` API operation to upload each part individually following the steps below:

*   Specify the `uploadId` obtained from the previous call to `CreateMultipartReadSetUpload`.
    
*   Upload parts for that `uploadId`.
    

When you have finished uploading parts, use the `CompleteMultipartReadSetUpload` API to complete the multipart read set upload and to retrieve the final read set IDs in the response.

To learn more about creating parts and the `split` operation, see [Direct upload to a sequence store](https://docs.aws.amazon.com/omics/latest/dev/synchronous-uploads.html) in the _Amazon Web Services HealthOmics User Guide_.
