DeepBinner on multi-fast5 followed by albacore on moved single fast5 fails.

[jnesme]

Dear Ryan,

I was wondering if the issue I'm having was already reported. I'm using deepbinner realtime locally to demultiplex Rapid Barcoding run. I've updated deepbinner to be able to handle multi-fast5.

I then upload the whole folder with scp -r to my analysis server where I want to run Albacore using a for loop on each barcode folder. I would have then concatenated the obtained fastq where both software agrees. It was working fine until recent MinKNOW update and the multi-fast5 but now I'm having this error in Albacore where it seems it can't read the single read fast5 files produced by deepbinner/multi_to_single_fast5 output. Here's what I'm getting from Albacore pipeline.log:

Any idea of what might cause this issue or should I forget about the double demultiplex solution ? I was going for the double demultiplex because we did notice quite a lot of barcode crosstalk and sequencing only novel DNA templates. I guess I could just use Albacore 2.3.4 on multi-fast5 and forget the deepbinner signal level demultiplexing, although I liked the idea of being extremely stringent in the selection of reads incorporating the assembly - with Unicylcer of cours :) ...

Best regards and many thanks for those precious tools offered to the community.

ok sorry for posting this irrelevant issue to DeepBinner, the problem lies with using deprecated Albacore....
Works like a charm with Guppy on deepbinner sorted reads. It just lack then the two layers of barcode demultiplexing.
