I have a data set with some off-target reads at low depth. These off-target contigs assembly into small linear sequences, and they're causing Unicycler to pick a less-than-perfect value for k. I'm going to try tweaking --depth_filter to remove these off-target sequences. I've run Unicycler with the default value of --depth_filter=0.25 and also --keep 3. Can I rerun Unicycler with a different value of --depth_filter, and can it resume without having to rerun the SPAdes assemblies? Any other tips for dealing with low-depth off-target sequence?
