If your file ISA archive does not meet those standards and conventions, you may encounter an error when you upload it to the CSSI DCC Portal. Your file ISA archive will likely process successfully but the application will detail the error in the Status column. You may then want to address the error and upload again. A sample error message follows:
...
CSSI DCC looks for errors in three types of files that are commonly in an ISA -Tab archive:
- Data files: If there are more than 1000 missing data files for an assay file, only the first 1000 will be listed.
- Additional files: If files are found in your uploaded archive, but were not referenced in the ISA-Tab metadata, they are listed.
- External file references: The upload summary lists all of the external file references in your uploaded archive and notes whether or not they are verified.
After the upload completes, the error message appears in the Status column of the File Upload area on the project pageUpload Single ISA Archive tab. It provides an overview of the error and a link to the details.
Click the link in the status message. A page opens that details the status of the three types of files in the uploaded investigation fileISA archive.
The Missing Files section details each missing data file referenced in the metadata of the assays:
...
The External File References section lists external file references in your uploaded archive and notes whether they are verified or not.
If the portal can detect that the URL is valid without authenticating it, it appears in this list as “Verified.”
In all other cases, it appears as “Not Verified”Verified.”
