Hello everyone,

I have the following issue: With a FLIR VUE PRO R we take some images. Then when I want to proccess I need to use the GCP/MTP and the manual tie points, but I can’t see the preview of each image. This is the log:

[Error]: ImageViewer: failed to open image \<xxxxxx/Documents/pix4dmapper/imagen6/1\_initial/project\_data/normalised/prueba6.jpg\>!

Thanks for your time

Another thing is that my images are in TIFF format and the error says&nbsp;[Error]: ImageViewer: failed to open image \<xxxxxx/Documents/pix4dmapper/imagen6/1\_initial/project\_data/normalised/ **prueba6.jpg** \>!

If someone has the same error: after investigation it appeared that step 1. Initial Processing was not processed. Once you process step 1 the problem is solved.&nbsp;
