stuck when using srtm or dem

[JulesFleury]

Hi,
I'm trying to do some tests with s2p. It works for now with small images, but results are not good compared to ASP or MicMac. Probably I don't know the good parameters.
I use Spot 6/7 images.

My problem is when trying to input srtm or external dem. In this case the process is stuck at "discarding masked tiles...", wether without using any dem it processes directly for this step.

Other question, when using the MicMac stereo, do we need to specify some parameter in the config.json ?

thanks for any help,
Jules
