Hi, the function would need to be modified since it currently requires the .scaffolds.tdt file right now. Here's an example below of what that looks like.

It might be a while before we could work on that, so in the meantime if you think you can just spoof that format that might be the fastest way.
Thank you very much. It looks tricky, but I'll try.
Hi,
If you have a fasta file for the reference genome and another fasta file for your query scaffolds, You can run your fasta files through minimap2 to generate a PAF output file, and then use the PAF file as input into PAFScaff. PAFScaff then generates the scaffolds.tdt file that you can use with the Ideograms.
Is that what you had in mind, or am I perhaps misunderstanding what you were wanting to do?

Thank you for your response, Bradley. Maybe I didn't make myself clear; I mapped the reads for bgc to the draft sequence of the study species with a gff file (almost at the chromosome level) and use this information instead of the reference genome of the other relative species. Perhaps I should also look around other packages to draw an ideogram.
Oh ok. Now I understand.
I'm going to mark this as a requested feature that we will try to get to in the future.
In the meantime, if you don't want to use the PAFScaff files to make the ideogram, you can try to write your own script to use the RIdeogram package (https://cran.r-project.org/web/packages/RIdeogram/vignettes/RIdeogram.html), which is what we used under the hood to make the ideogram plots. In the script you'd just have to get your data into a format that ideogram accepts.

Thank you very much, Bradley. I was thinking about the rideogram. The ClineHelpR helped me a lot. Thank you again. -Makiko
Hello,
This R package helps me a lot! I am trying to plot an Ideogram with the output of bgc. The species I am working on has a draft genome and I aligned this to the chromosome level before running bgc. Is it possible to plot the output with our fasta data which we mapped the reads or something, instead of pafscaff output file? Alternatively. perhaps I can create a dummy file of .scaffold.tdt in pafscaff. Can you give me details of the contents of the .scaffold.tdt?
Thank your very much in advance!
