“Image integrity issues in the scientific literature are more prevalent than many readers would expect, and notably so in the life sciences. In recent years, an increasing number of scientific journals have adopted pre-publication image screening. Expertise in this area has developed, whilst the need for reliable and user-friendly automated tools to screen large volumes of image data at scale has grown accordingly.  

​

I have found Proofig to be impressively strong in detecting duplications and part-duplications in Western blots and microscopy images. It works fairly quickly and reliably across several figures, whilst being robust to rotation, flipping, resizing, and colour changes. The makers recently also added Flow Cytometry plots to their catalogue of screen-able image types.

The system automatically generates a report summarizing individual, selectable findings in a clear manner, and users can also re-visit previously screened items in their own database. Whilst it remains essential for an experienced user to verify and interpret individual findings, I believe Proofig is a very valuable tool for duplication detection, and suited to effectively assist journals’ image integrity screening routines”.
