Hello Asun,

3- one read can produce more than one high quality segment

2- in your case, the counts are related to the number of blast hits that meet 
the criteria you put in the mega blast application. There are many blast hits 
per high quality segment.

1-after fetch taxonomic representation first run "find lowest diagnostic rank' 
and then run the summarize taxonomy and draw phylogeny tools. This should work.

I am trying to analyse my eukaryotic metagenome data using yours workflow for 
windshield splatter analysis. But I find several problems:

1- it is related to "draw phylogeny", this tool fails always for most of my 
samples, reporting the error: incorrect tree structure. Tree string position 341

2- It is related with the "summarize taxonomy" step. I this case I obtain 
results but the number of counts are too high compared with the original reads. 
My samples are small, around 8000 reads and the counts obtained are more that 
200000 for some phyla. I guess this is not ok, as far as I understand from your 
paper than counts are equivalent to reads, am I right?

3- another strange thing is the fact that the number of sequences increase 
after run the step for select the high quality segments. Any reason for this???

I will really appreciate you help. Thanks in advance
