@mdrphd hmm, thanks, I'll look into it.
@mdrphd So you have 11 libraries, each of which might contain technical replicates, and you are demuxing each separately, and then you'll combine them with merging after step 1, right? But you're finding that technical replicates are not being properly identified within each library yet, so you haven't gotten to merging yet.

@dereneaton Yes. That is exactly right.

@dereneaton @isaacovercast Hi guys I have a problem with system usage on a server running an ipyrad job of two samples. I have two samples with really large datasets and I have branched them following Darens helps but its using way more resources than I have allocated to it. This is the command I used
ipyrad -p params-Carm2.txt -c 48 -t 24 -s 3 -r >& Carm2 &

@Cycadales_twitter I was just talking with someone else about this. Step 6 currently is set to use all available cores during vsearch clustering, so it ignores the -c and -t options. The next release will fix this so you can limit it with -c or -t, technically by min(c, max(t, 10). So it will use 10 threads unless -t is set to a higher value, but t can't be greater than c. A bit complicated but it seemed like the best option.

@dereneaton ahh ok I see! Thank you that helps loads

Oh, but are you running step 6? Step 3 should be properly threaded, so in your case the vsearch jobs should be running 2 jobs with 24 threads each. But it looks like there are many more vsearch jobs running concurrently...

@dereneaton No I am running step 3.

If the assembly only has two samples in it then it shouldn't be possible to have more than two vsearch jobs running... maybe I'm not understanding something...

Hi @dereneaton @isaacovercast, I'm trying to create a catalog of loci to use as a "reference genome" for a non-model species, and I'd like to include loci that do not have SNPs. So far I've been using the x.alleles.loci file to create one, but this one only includes sequences with SNPs. Are there any intermediate or final output files that I have overlooked that I could use to create such a catalog? Is there an option to get more intermediate files during the ipyrad steps? Thanks!

@dereneaton there was only two samples so I have had to stop the job as I am unsure what the system is doing. As its using the whole cluster
server sorry

@nclowell The *.alleles.loci file should work fine for this, it does include invariable loci. Here's an example from an assembly I just did yesterday:
//                                                                                                                               |16|
@nclowell To answer your other question, if you re-run any step with -d it will print more debug output and also it won't clean up most intermediate files....
