LabCAS client-tools

Windows-based upload tool

For relatively small uploads the web upload tool works well. For large uploads, however, it can be a bit slow for convenience. For this reason we provide the option of uploading files using iRODS through a small pre-configured windows client.

  • Before you can upload files to LabCAS an upload key must first be acquired. To obtain this key follow steps 1-5 of the “Uploading Data” section above, providing the required dataset information.
  • Once a key has been obtained launch the LabCAS windows upload tool. A link to the installer will soon be provided here.

  • Enter the upload key in the top box then proceed to add files to upload by clicking the ‘Add’ button and selecting the desired files. This can be done multiple times before initiating the upload, allowing you to add files from different folders if needed.
    • Note: at this time LabCAS stores files in a flat structure. If grouping is needed for an upload it should be accomplished through naming conventions.
  • Check “Overwrite Duplicates” if files within the batch are being updated or re-uploaded rather than uploaded for the first time using this key.
  • To begin the upload process click “Start”. A bar will appear at the bottom of the window showing upload progress.
  • When the upload is complete a popup will appear confirming completion and giving information about any files which may not have uploaded properly.
