What is this tool?

This application allows you to generate an ASL parameter report to be copied into the Methods section of paper. The program will validate the ASL datasets by checking for inconsistencies, invalid values, and providing warnings for slight variations. Please ensure that your dataset is organized according to the BIDS standard before uploading or you can upload DICOM files and the program will convert them.

Here are some sample folders for you to download and test:

How to Use the Tool

Steps:

  1. Click the Choose Folder button and select the BIDS or DICOM folder containing your ASL data.
  2. The application will process your files and display the results below.
  3. For uploaded DICOM files, the application will convert them to BIDS format and process them.
  4. For BIDS the xxx_asl.json and xxx_asl.nii or xxx_asl.nii.gz files will be processed.

Note: The following specific checks and summaries will be reported:

  • Inconsistency Check: Discrepancies between values across different sessions, such as variations in PLD, labeling duration, echo time, and voxel sizes.
  • Invalid Values Check: Identifying values that do not meet predefined criteria, such as incorrect numeric ranges, boolean values, and string values.
  • Slight Variation Warning: Highlighting values that might not constitute a major error but are worth noting.
  • Generated Report: The software generates an ASL parameter report to be included in the Methods section of paper.
