Dear string MLST author,
we encountered an issue while testing your software on Enterococcus faecium. The error reported is:

The sample SRR980587 used for testing has been downloaded from:
www.ebi.ac.uk/ena/data/view/SRR980587.
Enterococcus faecium data are not present in dataset folder so we added it downloading allele files from PubMLST.
We created the config file following your README instructions:

The order of the alleles can be different when using different strain name
i.e
Sample mdh gyrB recA fumC purAicd adk ST
strain1 1 1 2 3 4 5 5
Sample purAicd adk mdh gyrB recA fumC ST
strain2 4 5 4 1 1 2 3 5
Makes it difficult to merge the two individual runs together into a single report.
Output kmer depth for each allele profiled. Can be useful for determining why stringMLST fails to give type something -- e.g. too low or no of coverage -- and for non-MLST screens (such as AMR)
Hi,
I just installed stringMLST through bioconda on my VM (Ubuntu 18.04 LTS on Windows 7 host) and ran it on a bunch of samples using E coli 1 MLST scheme. About 80% of the samples gave a ST and 3.5% returned 0, which were expected.
However, for the rest 16.5%, some returned an empty list and some gave a traceback error message. All of these problem samples were downloaded from NCBI. I had no problem running them in QC inspection or reference sequence alignment (bowtie2/samtools, etc.) so I know the files were not corrupted. Nevertheless, I did notice that most of the samples that returned an empty list were submitted from one source and contained contaminating reads from another serotype. I didn't observe any pattern for the ones that gave me a Traceback error other than the fastq.gz files might be on the small side (<50 MB each). I was wondering if there's an explanation, and better, a fix, for these samples.
Please see examples below (Ec is the prefix I gave E. coli MLST scheme 1 when I created DB):
ST = stringMLST.py --predict -1 DRR015930_1.fastq.gz -2 DRR015930_2.fastq.gz -P Ec
print(ST)
[]
ST = stringMLST.py --predict -1 ERR1777574_1.fastq.gz -2 ERR1777574_2.fastq.gz -P Ec
print(ST)

Hey there,
I'm attempting to run stringMLST for a cgMLST scheme.
I'm about to build everything to make it run, I have the allele fasta files, and will now create the profile file, where all the cgMLSt types and the alleles are listed.
Since it's a cgMLSt scheme, not all genes do have an allele in all cases.
I have multiple profiles, where some alleles are put down as "?" in the definition at the cgMLST website.
Do I also put a ? in the profile file? Or something else?
Any advice :)?
(I'll try anyways with a ? in there)

Hi all,
We have a user running stringMLST v0.6.2 --getMLST command for neisseria spp. However, the --getMLST step seems to be pulling down an empty directory called neisseria_db:
As you can see from the image: the n--getMLST step produces an IndexError IndexError: child index out of range and also creates an empty directory called neisseria_db which doesn't have the nmb subdirectory (which is mentioned in the quick start guide). Any advice on how we can proceed with this or if we are doing something wrong?
Best,
Nishant Gerald
Hi Aroon,
Happy New Year.
I noticed a discrepancy between the time reported with "-t" option by stringMLST and the time measured by /usr/bin/time -v.
This is what is reported by stringMLST:

ERR026529 231 180* 306 612 269* 277* 260 10174 7.67
And this is reported by /usr/bin/time -v

System time (seconds): 1.82

Why are they different?
Bests,

Handle broken links, empty files and odd HTTP status codes more gracefully. Currently, stringMLST crashed when it encounters bad input. This is increasingly becoming an issue, pubMLST have pushed several empty or otherwise malformed profile definitions over the last month.
This will also help address jordanlab/stringMLST_datasets#1
Currently some function calls are not compatible with python 3.5+
modernize
The apostrophes on lines 114 and 163 were causing an error. "SyntaxError: Non-ASCII character '\xe2' in file /home/username/.local/bin/stringMLST.py on line 164, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details"
Not sure if this is unique to my system but removing these resolved the issue.
Hi, I am using stringMLST and I noticed that I got different results for running the same sample more than once. The database changed (updated). What was surprising that some of the assigned ST's in the first run were completely different in the second. is this normal?
No matter how high I set the -z value, there are no stars. Removing the backslash in the line below fixes the problem for me.

Hi everyone,
I have some issue, which is... confusing.
I used stringMLST before, succesfully with a cgMLST scheme, and the results seem to make sense.
For another project, I also ran some data with stringMLST through the same scheme. The results also kinda make sense, but not quite. Basically, we had a few strains, which we are really, really certain that they are clonal. The result of stringMLST is that they are all slightly above the accepted threshold for clonality (which is probably not valid, but that's not the point right now).
So I had a look at the diverging allel predictions. I mapped the reads with bowtie2 to all first allels of the cgMLST (which is like 2200), and inspected the mapping of the diverging allels, manually, in a genome viewer, just to be certain.
And the diverging alles are the same between at least 2 of the samples. stringMLST predicts them different, but the mapping is the same.
The diverging allel predictions are not tremendously off (like 1 or 2 bp), but they are still wrong.
The affected allels are affected over multiple samples, so this also seems to be systematic.
Any idea what could be the cause of this?
This affects version 0.6.2, in case this matters.
Regards,
Bastian
EDIT: The very samples I am taking about are ERR2232520 and ERR2232524 .
I used this scheme https://www.cgmlst.org/ncs/schema/3560802/ , and affected allels are for these 2 samples are 03340, 04010, 08730, 08930, 10560, 13310, 16340 .
e.g. allel 08930 is predicted to be different over 5 samples, which we expect to be the same (different prediction in all 5 samples), so this is probably systematic.

Created database for Listeria monocytogenes from http://bigsdb.pasteur.fr/listeria/ and it finished correctly. However, when running the prediction, one allele was missing from the results and no ST type were found.
Looks like the issue is with this section of code: https://github.com/anujg1991/stringMLST/blob/master/stringMLST.py#L438
The script always assume there is only ONE extra column at the end of the ST. In Listeria case, there are two extra columns "CC" and "lineage".
stingMLST.py --buildDB breaks if there is a 'U' in the multi fasta locus file because there isn't a key in the reverse compliment dictionary for 'U'.
What happens if strain has missing alleles? How does the user know it was missing?
When I tried updating my mlst database using --getMLST
, it failed with ssl errors. I was able to correct the problem by importing ssl
and adding in a line to ignore the certs. The attached version of stringMLST.py
contains the patched code. I've confirmed it works.

Hi,
I am trying to get stringMLST to work, and I am following the Quickstart guide.
Using this command line (after pip installing, downloading database and data):
stringMLST.py --predict -P neisseria/nmb -1 ERR026529_1.fastq.gz -2 ERR026529_2.fastq.gz
I get this result:
No k-mer matches were found for the sample ERR026529_1.fastq.gz and ERR026529_2.fastq.gz. Probable cause of the error: low quality data/too many N's in the data
Sample ST
ERR026529 ST
I checked both data and database, that seems to be alright.
OS: Ubuntu 14.04
Python: Python 3.6.0 |Anaconda 4.3.1 (64-bit)
I have been using the stringMLST with a pubMLST database. However it is missing new alleles that have been identifed in the isolates using two other methods. I tried to adjust the -z parameter incase that would help but I only got the response that the various numbers I tried - 100, 500, 400, 350 were not intergers.
What happens if a strain contains an allele but it particular sequence is unique to the database? How it is represented to the user? SRST2 represents it with a * character beside the allele number.
Sorry, need to ask again something.
When I try to build the DB, I get the following:
Info: Making DB for k = 35
Info: Making DB with prefix = /exports/mm-hpc/bacteriologie/bastian/data/Cdif/cgmlst/stringMLST_db/cdif_cgmlst
Info: Log file written to /exports/mm-hpc/bacteriologie/bastian/data/Cdif/cgmlst/stringMLST_db/cdif_cgmlst.log
Error : Allele name in locus file should be seperated by '_' or '-'
I'm unsure to what it refers to.
My fasta files with the different loci are called e.g. CD630_00010.fasta , but the names of the fasta entries are only integers (>1, >2, >3). Do I need to change these fasta headers?
In the profile file, does it then still need only the integers, even if I rename all the headers to e.g. >CD630_00010_1, >CD630_00010_2 etc?
Am I guessing correct here?
Thanks,
Bastian
When downloading the master branch as a zip file, the total size is 160.98M which is HUGE for a code base. Perhaps replace example read files folder with a script that would download them separately instead.
It is taking over 15 minutes to clone the repo now.
Could not built database because some of my sequences contain lower case characters. Got the following stack trace:

Looks like the reverseComplement function only works on upper case character. Perhaps you should convert all input sequence to upper case first before attempting to do reverse complement.

When running the Strep pneu against the Listeria Mono. to see what a failure looks like I get the following result.
No k-mer matches were found for the sample . strain_R1_001.fastq and strain_R2_001.fastq. Probable cause of the error: low quality data/too many N's in the data
Sample ST Time

Noticed in the code that the No k-mer match statement was followed by exit statement but it was commented out. I think reporting back to the user with N/A or no result would be best instead of just exiting . If someone is running in batch mode or combining individual results together, its very usefully to know which strain actually had no result. If they do not show up at all, then no idea if the software failed or because no k-mer found.
Hello @ar0ch,
I am using stringMLST and get ST assigned in terminal but log shows several lines of `"ERROR while loading ST".
Can anybody help?
Hi,
Thanks for your work on this tool. I'm interested in pairing it with rMLST like you describe in the original paper, so I obtained the database and have been trying to build a kmer database for classifying samples. However, the memory required seems to be far above 128 GB, and I've killed the build script before the OOM killer activates.
Any advice on building the DB? I suppose I could do it on AWS if needed, or construct the DB manually using jellyfish.
Hi!
I ran stringMLST on the sample from EBI SRA database ERR024377 (S. enterica):
stringMLST.py
--predict
-1 ERR024377_1.fastq.gz
-2 ERR024377_2.fastq.gz
-k 35
--prefix ERR024377
--output res.txt
and the res.txt file contains the following:
Sample aroC dnaN purE ST
ERR024377 345 342 0 0
Since the loci are totally 7 (aroC, dnaN, hemD, hisD, purE, sucA,thrA) , what is the difference between purE which got a 0 and hemD, hisD, sucA, thrA which got an empty value?
