Guys, If you have more than one box/tiff pair, you can train (i.e. generate a .tr file) for each of these pairs separately.
Then you can concatenate (simply "cat" or "copy") all resulted .tr files together and then run all training tools on the single final .tr file. This relieves you from the 32 file limit. For your convenience you can craft a batch file or shell script which would train, concatenate, cluster, etc. in one run. You should analyze all errors carefully though.
