I've been using ipyrad for a while but i now have a problem.
I've sequenced 5 pairgbs librairies of about 96 individuals from 10 different species.
I used ipyrad to demultipex each of the 5 libraries separately (cause i can't mix different individuals that share the same barcode in the step 1 and 2). Now i want to proceed step 34567 for each species. The problem is each species is split into the 5 different librairies, i thus need to specify 5 paths to demultiplex data instead of 1 path. I don't know how to do so. The program don't allow me to do that. I also tried to make a new directory where i copied the demultiplex files from all of the 5 libraries fro one species and tried to run ipyrad -b ... -p ... from there. But the program don't allow me to do that neither. I tried to copy the .json file but there is 5 different .json files so how to choose one? Is there a way to concatenate the 5 .json files to make one big .json file so that the program would proceed has if i demultiplexed all the reads for the species in one time and not in 5 times?
Thanks in advance!

@isaacovercast That seems to have worked. Thanks! One question - how do I know if the analysis is running? I see that the input files were created successfully. All I see in the "Running" tab of the Jupyter notebook though are a terminal and the notebook.

Hi! I am working with a collaborator to run some (already demultiplexed) 3RAD data through ipyrad. We get through steps 1 and 2 okay; and through step 3 for some of our samples, but when we hit a particular one we throw a "list index out of range" error similar to a previous ticket (#291 I think).

Here is some of the text from the debug log near the error:

@tommydevitt If you look at top you should see running ipcluster engines.

@isaacovercast Thanks. Looks like there's one instance of ipcluster running. Should there be one for each core specified, or just one total?

Hi, I have a question about the potential differences between the number of retained loci listed in the .stats file vs. the .u.snps.phy file. For some of my datasets, I see that the two files match and both report 1,000 loci/unlinked SNPs (just an example), but then for other datasets, the stats file may say 1,000 loci, but then there's only 900 in the .u.snps.phy. I also see this pattern with my .vcf files. I'm just curious as to why there would be this difference. I'm assuming that those 100 are invariable and so not included, but just wanted to double check.
