Manually merging labeled segments


Context

*Hi there, I am trying to generate a segmented image to be used in a landuse classification random forest model. I am running this on a high performance cluster, however I am limited to 8 hour session time limits. While running the LSMSSegmentation tool, it generated all of the individual tiles (92,584 in total, it is a big area) but it didn’t generate the merged labeled tif file. So I can’t run the next tool in the process which is the LSMSSmallRegionsMerging tool because it is looking for this merged tool.

Can I just merge all the individual tiles together? Or use a virtual raster? Or do I have to re-run the entire tool again?*

Configuration setup

My system: Linux?
Version of the OTB: 9.0?
I installed the OTB with: the binaries

If relevant, you may also provide:
Python version: 3.10 but in a virtual environment

Description of my issue

As mentioned, if the LSMSSegmentation tool is stopped before generating the final merged labeled tif file, can I just merge the individual tiles manually?
