If you can send me your files I can find out what is wrong with them. I'm sorry it's been frustrating.

Hi meren,

I finally figured out the correct format for alluvial illustrations (on "https://app.rawgraphs.io/").

Just need to generate a table with contig names on first column and bin names on the rest of columns. Something like the following:
Contigs | maxbin | metabat | metawrap | concoct
c_000000000502_split_00001 | maxbin_bin32 | metabat_bin63 | mv_bin31 | concoct_bin95
c_000000000512_split_00001 | maxbin_bin32 | metabat_bin63 | mv_bin31 | concoct_bin95
c_000000000571_split_00001 | maxbin_bin32 | metabat_bin63 | mv_bin31 | concoct_bin95
c_000000001297_split_00001 | maxbin_bin32 | metabat_bin63 | mv_bin31 | concoct_bin95
c_000000001297_split_00002 | maxbin_bin32 | metabat_bin63 | mv_bin31 | concoct_bin95
.......
There are actually multiple ways for doing this job.

Appreciate this idea for using alluvial figures to compare binning results.

Thanks!

#Hello,

#I am having some trouble getting this script to run.

#I have modified the algorithms sections as follows

algorithms = OrderedDict({'ANVIO_CONCOCT': G('collection-Concoct.txt'),
'ANVIO_METABAT': G('collection-bbmap_Metabat2.txt'),
'MANUAL_METABAT': G('collection-manual_metabat_bins.txt'),
'DASTOOL': G('collection-dastool_bins.txt')})

#My files are located in the same folder as the script and were exported from anvio through anvi-export-collections.
collection-bbmap_Metabat2-info.txt collection-Concoct.txt collection-manual_metabat_bins-info.txt
collection-bbmap_Metabat2.txt collection-dastool_bins-info.txt collection-manual_metabat_bins.txt
collection-Concoct-info.txt collection-dastool_bins.txt

#I have been running the script as follows
python anvi-script-gen-alluvial.py

#I also had to add a line that imports anvio at the start of the script otherwise it was unable to find a module named anvio.utils.
import anvio

#Now the issue that I am running into is this:
Config Error: That algorithm we don't know. This is what we know: ANVIO_CONCOCT,
ANVIO_METABAT, MANUAL_METABAT, DASTOOL.

#So i guess it is getting stuck as that first if statement. I am not super familiar with python so any help would be greatly appreciated.

#Thanks !
#Claudia

#FIGURED IT OUT!
need to have --algorithm and --bin flags to run

for example
python anvi-script-gen-alluvial.py --algorithm ANVIO_CONCOCT --bin Bin_27
