Pathway Tools is not in the Path, mpwt can not work without it. about mpwt HOT 23 CLOSED

Hi @ChenCongZ,

This message indicates that Pathway Tools executable (pathway-tools) is not available in the path environment variable. Have you installed Pathway Tools and add it to the path?

To add Pathway Tools to the path variable after its installation is explained in the readme:

https://github.com/AuReMe/mpwt#requirements

For Linux and macOS it is by using the following commands:

echo 'export PATH="$PATH:/your/install/directory/pathway-tools:"' >> ~/.bashrc
source ~/.bashrc

For Windows, you must add the path of the pathway tools folder to the Environment Variables. Open the Environment Variables window, select the Advanced system settings, Environment Variables. Then crate a new variables in the System variable.

But mpwt has not been tested on Windows, so I do not know if it works.

Dear Mr AuReMe,
I run it in the window and put it in the System variable. Please check below.

Hi @ArnaudBelcour,
Its installation location is C:\Program Files\Pathway Tools according to https://github.com/AuReMe/mpwt#requirements. So it must be my installation problem or its path setting problem. However, I also tried many changes. No key problem was found.

I tried it, too.

I think there is no problem with your installation of Pathway Tools.

For your environment variable, I think that there is an issue. The variable column (变量) of the System variable window must be path to add the path of Pathway Tools and not C:\Program Files\Pathway Tools to have access to the executable files in the path. But this will give access to the path to executables such as ptools.bat and at this time mpwt does not handle these scripts (and I am not sure if it will handle them one day). Especially since I do not have the time to make these modifications.

As I have explained in my first post, we tested and used mpwt only on Linux and macOS. On Windows, I have only used using the Windows Subsystem for Linux (by installing the Ubuntu subsystem on it and then installing the Pathway Tools installer associated with Linux), otherwise I do not think that mpwt can work with the powershell.

Hi @ArnaudBelcour ，
Thank you for your help.
This problem occurred when I installed Pathway Tools, and I suspect that my window system can't read it. However, I have tried many methods, but I can't find the key installation problem. Can you check it for me?

Warning: EnableWindow: (error 127) 找不到指定的程序(The specified program could not be found).

from mpwt.

I made the changes according to your suggestion.

Hi @ArnaudBelcour ,
Thank you for your help. I have solved the problem of the path. Can you tell me the version of the Pathway Tools used in testing "Metage2Metabo\test\metabolic_data\toy_bact"

from mpwt.

Because I want to get toy_bact SMBL format in testing "Metage2Metabo\test\metabolic_data\toy_bact"

Hi @ArnaudBelcour,
This problem always occurs when I run Mpwt.

Hi @ChenCongZ,

I do not think that the error comes from your installation of Pathway Tools.
mpwt is not working on Windows (as the binary and paths seem to be different from the ones of the Linux/macOS versions) and I have not the time and resource to work on this.

Hi @ArnaudBelcour,
Thank you for your suggestion!
Recently I tried to solve these problems with ubuntu ( linux operating system) and got some progress. At the same time, I encountered some problems in the mpwt pipeline. It shown below:

from mpwt.

I used your data to get some results in the mpwt, but I have a question: I get XML data format like this, not the same as you get.Does this have an impact on M2M pipeline analysis?

from mpwt.

Hi @ChenCongZ,

For the first issue, it comes from the taxon_id.tsv file (for more information look at the readme). There are issues in the format, this file must look like:

The taxonomic ID corresponds to the taxonomic ID associated with your organism in the NCBI taxonomy database. For example, here 562 corresponds to Escherichia coli.

For the XML files you created, yes this will impact Metag2Metabo results. You created these files using the --mx (in command line) or the xml_extraction (in python) option. This extracts XML files created by Pathway Tools. These files are different from the ones created by Metage2Metabo as they are created by the padmet package.
There are multiple differences such as different IDs, the XML from Pathway Tools will contain instantiated metabolites from metabolite class whereas SBML from padmet will only contained the classes.

If you use this as a test to find similar results, you need either to give the flat files (obtained with --md or dat_extraction) to Metage2Metabo or to launch Metage2Metabo with recon on your the same folder.

Hi @ArnaudBelcour,
Thank you for your suggestion!
This prompt came up today when I reconstructed the metabolic network model of the test data based on your reminder. However, I don't know which step I overlooked.

reconstruction.recon('/home/chencong/test','/home/chencong/output3',noorphan_bool=True,padmet_bool=False,sbml_level={2},nb_cpu=2,clean=True,use_pwt_xml=True)

I also checked its status.

Hi @arnaud Belcour,
AttributeError: 'xml.etree.ElementTree.Element' object has no attribute 'getchildren'.

from mpwt.

Hi @ArnaudBelcour,
I'm very sorry to bother you when you are busy, but I have encountered many problems during the reconstruction of metabolic pathway in a few days. I can solve some of them, but my limited ability can't solve all of them. I'm confused that I reconstructed metabolic pathway data by directly using the data annotated by prokka after binning. The annotated file (.gbk) of an organism is divided into several sections, and the specific files are listed below. Can files like this be directly used for data input without m2m?
bin.4.strict.txt

from mpwt.

Hi @ChenCongZ,

Yes this file can be used as input for mpwt/m2m. You need to change its extension (from txt to gbff). Furthermore, you need to use a taxon_id file to indicate the taxon ID corresponding to this file as there is no taxonomic information in the gbff file created by Prokka.
The different sections in the gbff file (called Locus) correspond to the different contig contained inside this bin, Pathway Tools will handle them without problems.

Hi @ArnaudBelcour,
Thank you for your help.
I've got the single species sbml file.
But I encountered a problem converting seeds metabolites file.

from mpwt.

Hi @ArnaudBelcour,
Thank you for your help.
I've fixed these issues, thank you for your help.

from mpwt.

Hi @ArnaudBelcour,
I can run all the other results,but there is a issue about m2m.recon.
