Hi group,

We are processing a large data set, and the “Calibration” step on “initial processing” is taking days.&nbsp;

It advanced fast to 82% but each percentage&nbsp;advance since 82% is taking over 12 hours.

From the screenshot below, you can see that there are two areas (area 2 and 3) that are separate&nbsp;from the main area, is this causing the delay?

Also, does anyone know if it will be able to finish&nbsp;this process?

Hi Alan,

At the moment we can’t see the picture you attached. We noticed some platform issues that soon we report. Therefore could you upload the screenshot as well as the following files to our [OneDrive](https://pix4d365-my.sharepoint.com/:f:/g/personal/beata_ciesielska_pix4d_com/ElsBiNcVOfpBt9-LIvsNZZ8B1aiF-M2oEfTnG6Sgacjqsg?e=u3TkaV)? We would need to have more data to investigate the issue properly.

▸ The quality report (.pdf format): …\project\_name\1\_initial\report\project\_name\_report.pdf  
▸ The project log file (text file): …\project\_name\project\_name.log  
▸ The project file (.p4d): …\project\_name.p4d

Additionally, please send us the machine specs:

1. Click the Windows Start icon and type System Information. Select the application in the list above.
2. In the application, click File \> Save… and export the content.
3. Attach the file your\_file.nfo to the reply.

I’m waiting for your reply.&nbsp;
