Hi @himadri2007 ,
There is a QIIME 2 plugin called RESCRIPt (which needs to be installed separately, follow instructions at the link below). It has an action for filtering sequences by both minimum and maximum lengths:
This will need to be run after denoising, however, so may or may not help your use case.
This will truncate all reads at position 200, and filter out any that are shorter. But indeed this will not filter out reads that are too long (it will only trim them).
Good luck!
