MCT Data Processing

← Back to MCT homepage

All experiment data will be stored in the Australian synchrotron for one year period. Please copy your data to your institutional data storage before the expiry date.

ASCI Desktop is used for data processing, reconstruction, and analysis. It provides a simple interface to the cluster computer at the Australian synchrotron. ASCI Desktop can be accessed → in this link, during the beam time and/or after the beam time. The experimental projection data and the reconstructed data are saved in hdf5 file format. However, they can be converted to tiff file format. MCT reconstruction pipeline is available in ASCI Desktop to reconstruct the projection data into 3D reconstructed data. See the detail instruction below:

The MCT reconstruction code is written in jupyter notebook. MCT reconstruction pipeline includes:

• TIE Hom phase-retrieval

• Tomography artifact correction such as beam hardening, ring correction

• Horizontal and vertical stitching algorithm.

For conversion .h5 file to .tiff file you can see below step:

For fine tuning the COR (Center of Rotation):

Analysis software such as ORS-Dragonfly and Avizo are also available in the ASCI desktop for 3D viewing, image rendering, image segmentation and other data analysis. The Dragonfly plugin to open .h5 file can be found in this link: https://github.com/AustralianSynchrotron/dragonfly_mct_import . However, Dragonfly is only available for online users or the users are having the beam-time.   

People who are listed in the Experimental Authorization Form will have access to the data automatically.

You can access to your experimental data remotely via Secure FTP (SFTP) to download your experimental data. You can use a graphical client such as FileZilla with the following connection details:
