Staff Analysis Only
The Zeiss Xradia Versa 620 XRM is only available for staff analysis. Below is step by step instructions on how to submit samples for scans and process data.
Sample dimension
- Smaller sample (i.e., powder vs solid) is better because detector and source can be closer to the sample, which will increase the X-ray counts and reduce measurement time. Max size <5 x 5 x 5 cm for a single scan.
- Sample need to be mounted (i.e., poke, glue, tape, clamp) on one of holders, please leave a note if the sample need to be recovered without any damage/mark.
- Sample cannot change its morphology during the measurement. (i.e., dehydration) This will result a failed reconstruction.
- For samples with high aspect ratio (wide or tall), wide-mode, or vertical-stitch will be applied, that may cause longer measurements.
Data Processing
- The main data processing software we recommend and use is DragonFly from ORS.
- The standard file you will receive is a session (.ORSSession) that contains one or multiple reconstructions. You can download the trial or apply a free non-commercial license on your own PC (check minimum requirements).
- You can also access Dragonfly software using the workstation at ECERF open area (this is a tool on LMACS). Please feel free to apply a Dragonfly software training to get access to the workstation. (SOP)
- There are also helpful tutorials to get start on Dragonfly.
Sample dimension
a. Session file (.ORSsession) is the standard file you will receive. It can be imported in any versions of Dragonfly software. (Trial version and non-commercial license available )
b. If you only need 2D projection, we can convert Zeiss proprietary format (.xrm) files to images formats.
c. We can also provided Zeiss proprietary formats (.xrm, .txm) if you have special needs. It can still be loaded in software like Fiji(ImageJ) with plug-in, but with only limited functions. Please discuss your needs with us first.
- Scanned results will be received
- file .session
- Dragon Fly
- nanoFAB workstation
- Academic users can apply for non-commercial license
- Scout-and-Scan softwarekey parameters: Pixel size; source energy; fan angle; sample, source, and detector location
b. recipe file (.rcp): recorded all the scan(s) parameters, useful for repeating similar samples
c. 2D projection files (optional, .xrm)
d. manual reference file (optional, xrm)
e. projection dataset file (.trxm): series of 2D images at different angles (typical scan is 1601 projections)
f. tomography drift file (.trxm): includes information about sample drift during measurements
g. reconstruction file (.txm): a stacking of 2D reconstructed images. Zeiss proprietary format
2. The Reconstruction software (optional):
a. manual reconstruction is need from time to time
b. import projection dataset file (.txrm) and output reconstruction file (.txm)
3. The Dragonfly Pro software:
a. import reconstruction file (.txm) and output session file (.ORSSession)
4. Notes:
a. Session file (.ORSsession) is the standard file you will receive. It can be imported in any versions of Dragonfly software. (Trial version and non-commercial license available )
b. If you only need 2D projection, we can convert Zeiss proprietary format (.xrm) files to images formats.
c. We can also provided Zeiss proprietary formats (.xrm, .txm) if you have special needs. It can still be loaded in software like Fiji(ImageJ) with plug-in, but with only limited functions. Please discuss your needs with us first.
