Unable to Render graph using RAST Annotations #44--FOLLOW UP about ppanggolin HOT 11 CLOSED

The latest commit introduces the new filter 'product' to display what can be found in the 'product' field of annotation files, which is what you were looking for I believe.

You need to install it from git, like last time, and you can use it as such:

ppanggolin spot -p ./pangenome.h5 --draw_hotspots --force -o ./hotspots-fuso-1/ --label_priority product,name,ID

for example, which will display the product if there is one, if not the gene name if there is one, and if not the gene ID.

I've updated the margins as well so that the display is not too bad, but there will probably be some overlapping labels.

Hi,

I managed to replicate the error, it comes from the '&' special character in the RAST annotations apparently. I've updated PPanGGOLiN's gexf writing functions to remove this character and managed to open the gexf generated by PPanGGOLiN afterwards.

The latest commit on the master branch should fix the issue. If you used conda to install ppanggolin, you can install the new version in your conda environment by cloning the repository and install as such:

git clone https://github.com/labgem/PPanGGOLiN.git .
pip install .

and then reuse the 'write' function to obtain the gexf again, as such:

ppanggolin write -p pangenome.h5 --gexf --output MYOUTPUTDIR

I saw in the gexf file which you provided that you use an older version of PPanGGOLiN (1.1.96). If you are in a constrained environment where you cannot update the tool easily, an alternative solution is to remove the '&' character from the annotation files which breaks the gexf format for some reason. It should work well after that.

Thank you for the bug report and your nice comment :)

Hi,

Thank you for quickly replying to this! I was able to render the graph after removing the '&' special character. I am now trying to generate the Spots of insertion figures using the --draw_hotspots command, but I am generating figures without any labels. Is this another issue related to the annotations, or am I using the command incorrectly?

I am running

ppanggolin spot -p ./pangenome.h5 --draw_hotspots --force -o ./hotspots-fuso-1/

The file appears to be too large to share here, so I can email if it would be helpful.

Additionally, if I am using PPanGGOLiN in a conda environment, can I update to add the fix you just pushed? Thank you!

from ppanggolin.

For the hotspot command, i've done multiple changes lately (related to other issues), so updating PPanGGOLiN will likely help you with the figure labels. There's actually an additional option to the spot command to control which information to use as labels, which makes things simpler. Details on how to use this option were given in this message: #56 (comment) (I've not updated the wiki yet)

If you are in a conda environment, you can just use the two lines I wrote in my first message while the environment is activated, it should work nicely. For the 'conda update' to work it involves making a new release, and then updating the bioconda recipe, which involves additional work for people other than me so I avoid doing it too often.

Hi Adelme,

Thank you for the guidance on this! I was able to generate figures with labels, but they seem to be only general ID's such as CDS_xxxx--is there any way to have the labels be the "Annotation" seen in the matrix like this:

from ppanggolin.

Hi,

It is not currently possible, but I can add it as an additional filter quite easily, I'll do that later today.
I'd expect the figures to be a bit hard to read though, but we'll see.

I'll tell you when the feature is on the master branch.

Hi Adelme,

This is great! This is exactly what my PI was hoping for, so I am very thankful that you pushed that change through so quickly.

Is there by chance a way you could add the ability to scale the label font size down as an optional parameter/argument? This screenshot is of a particularly crowded figure:

If that is not something that can be changed, feel free to close this issue! Thank you again!

Indeed that's quite unreadable. It's probably possible to do that, I'll take a look at it within a few days.

The latest commit on the repository adds a new option to the spot command "--fig_margin" which can help you increase the space between the represented RGPs.
Default is 100.
You can install the new version with the same method as previously.

I'll try to think of a better way to customize the figures in the futur.

Hi Adelme,

This is great! I appreciate your willingness to work on this and to push all of these commits through so quickly. The new '--fig_margin' option is working perfectly for our purposes.

Cheers,
