Ion torrent shhh.flows error

Hi there,

Having problem working with Iontorrent data.

sffinfo and trim.flows gets through.
However, output file “A1.trim.flow” is 1KB and “A1.flow.files” is 0 kb. But the scrap.flow has 2,777,754KB.

I get the following error message when i run mothur > shhh.flows(flow=A1.trim.flow, processors=8)

Unable to open C:\mothurGUI\mothur\lookupFiles\LookUp_Titanium.pat. Trying mothur's executable location C:\mothurGUI\mothur\LookUp_Titanium.pat

Using 8 processors.

i tried different commands for trim.flow i.e

mothur > trim.flows(flow=A1.flow, oligos=oligos.txt, pdiffs=1, bdiffs=1, order=I, processors=8)and also
mothur > trim.flows(flow=A1.flow, processors=8) and also
mothur > trim.flows(flow=A1.flow, oligos=oligos.txt, processors=8) none seem to work

FYI: i used v1-v2 region for 16s amplification;
and this is my oligos file

forward AGAGTTTGATCCTGGCTCAG
#reverse        CTGCTGCCTYCCGTA
barcode TTCGTGATTC     A1

can somebody help me…

thanks

First, you want to use order=I if this is IonTorrent data for both the trim.flows and shhh.flows steps.

Second, can you look at the first line of the flow file and tell me what the number is?

First line of A1.trim.flow is 450

however, its size is just 1KB.

I used order=I for both trim.flows and shhh.flows. No luck…

Sorry - what is the first line of the A1.flow file?

Thanks for the reply… The A1.flow.files is empty. with 0KB data…

Does this mean the read quality are bad?..

You should have a file called A1.flow. What is the number on the first line?

sorry… the first line of the A1.flow, is like this

850

What region are you sequencing? If you’re in mac/linux, can you run the following from the command line?

cut -f 2 -d " " A1.flow | sort | uniq -c | sort

And then post the results? It looks like it tried generating 850 flows, but for this sequence there were only 129 good flows, which would probably give you about 100 bp. If this is pretty standard for your dataset, then you’ll want to set minflows=120, maxflows=120. But post the results of that command and let me know what you get…

Pat

its a 16srRNA sequence of the microbiome, i amplified V1-V2 regions(approximately 350bp) and sequenced using Iontorrent PGM system.

i ran the commant u gave me through cygwin… and here are the result

could you please tell me how would i set the miniflow and maxiflow values.

thanks a lot for the help

After you run trim.flows with flow=I and whatever else you are doing (post the full command, please), can you run the following…

cut -f 2 -d “|” A1.scrap.flow | cut -f 1 -d " " | sort | uniq -c

… and post the output?

It looks like the length is okay, so I suspect there’s a barcode or primer issues

Pat

Thanks for the reply,

I used the following commands until trim flow
mothur > sffinfo(sff=A1_sepsis.sff)
mothur > trim.flows(flow=A1_sepsis.flow, oligos=oligos.txt, pdiffs=1, bdiffs=1, order=I, processors=8)
mothur > shhh.flows(file=A1_sepsis.flow.files, order=I, processors=8)
the results are as below.

Things are getting tossed because of the barcodes and primers in your oligos files are likely incorrect. Can you run:

trim.seqs(fasta=A1_sepsis.fasta, oligos=oligos.txt)

Does anything go to the trim.fasta file? I suspect no…

If you can compress and post the flow and oligos files to dropbox or google drive I can take a look. Also, please include the url for this post so I can remember what the issue is.

pat

i had amplified the V1-V2 region using the same Forward and Reverse primer given in oligos file.

And you are right. when i ran trim.seqs(fasta=A1_sepsis.fasta, oligos=oligos.txt), none went to trim.fasta file… everything is in scrap.fasta.

this is my oligo file

forward AGAGTTTGATCCTGGCTCAG
#reverse        CTGCTGCCTYCCGTA
barcode TTCGTGATTC     A1

i will compress the flow file and oligo file and mail you…

thanks a lot

Rosh

I think you’ve got the wrong barcode sequence. When I picked a sequence from your flow file (XMCD4:00058:01166) and translated the first 30 bases I can find your forward primer, but not the barcode sequence. What I see is TTCCGATAACGT, not close to your TTCGTGATTC - the lengths are even different. Can you double check that you’ve got the correct barcode sequences?

Pat

Thanks a lot for the help… i will check the barcode and try to redo the process again. hope i can get it smoothly…

Thanks a lot for the valuable suggestion. i could see that the Barcode sequence was wrong. I used the right barcode sequence and was able to pass through trim.flow. However, A1.scrap.flow had 2,410,256KB… A1.trim.flow had 195.107KB. i guess most of the reads were filtered into scrap.flow.

I tried proceeding with the shhh.flow… i got this error this msg :[ERROR]: std::bad_alloc has occurred in the ShhherCommand class function driver.

[ERROR]: std::bad_alloc has occurred in the ShhherCommand class function driver. This error indicates your computer is running out of memory.  This is most commonly caused by trying to process a dataset too large, using multiple processors, or a file format issue. If you are running our 32bit version, your memory usage is limited to 4G.  If you have more than 4G of RAM and are running a 64bit OS, using our 64bit version may resolve your issue.  If you are using multiple processors, try running the command with processors=1, the more processors you use the more memory is required. Also, you may be able to reduce the size of your dataset by using the commands outlined in the Schloss SOP, http://www.mothur.org/wiki/Schloss_SOP. If you are uable to resolve the issue, please contact Pat Schloss at mothur.bugs@gmail.com, and be sure to include the mothur.logFile with your inquiry.

My computer is Octa-core i7 with 16GB RAM. it tried running it with processors=1, it gives the same error.
this is the summary of the fasta file i got after sffinfo.

Any solutions?..

thanks…

That error is due to your distance matrix being so large that it crushes the RAM supply. You could use a computer with more RAM, use MiSeq, or use a quality score-based method. Your distance matrix is so large because you have so many unique sequences due to the high IonTorrent error rates.

Sorry, IonTorrent is a really bad platform for 16S.

Hi,

We did the sequencing again with 8 metagenomic samples(multiplexing) in 314 chip using PGM-ion torrent machine. However, when the sequencing completes it gives the individual samples seperated by barcodes.
sffinfo gets through. when i do the trim.seqs, the resulting flow.file is empty , scrap.flow file shows 47MB, trim.flow file has 1kb…thus i am not able to proceed further… Does this mean the sequencing went bad??..

sorry for the trouble again. we really wanna perform the analysis using MOthur as we cant depend upon online pipeline because of time.

Sincerely

rosh

The main problem is that IonTorrent really should not be used to sequence 16S rRNA genes. The error rate is huge and just causes tons of problems. You are not the first person to experience this problem. It’s a shame that when you resequecned the samples that you weren’t able to do it on the MiSeq.

Your specific problem is likely still due to some problem with the barcodes that you are using for your analysis not being the same as what you used to do the sequencing…
