Error in gtfs_merge(gtfs_all, force = force_merge) : Duplicated Agency IDs 2

[bghjmn32]

Hi,

I am a beginner student in GIS area (also R). I am trying to use this library to transform TNDS data. Thanks for your work firstly!

Your demo code works for me.

library(UK2GTFS)
path_in <- "TNDSV2.5/EA.zip"
gtfs <- transxchange2gtfs(path_in = path_in,
          ncores = 8)

gtfs_write(gtfs, 
           folder = "/home/UK2GTFS/output",
           name = "gtfs_EA")

However when I try to apply this code to different files from TNDS dataset such as EM.zip, L.zip...etc. It always show me this error:

2023-11-02 14:28:00.921419 Converting to GTFS, multicore

|=============================================================================================================================================================================================================================================| 100% All files converted Error in gtfs_merge(gtfs_all, force = force_merge) : Duplicated Agency IDs 2 Merging failed, returing unmerged GFTS object for analysis

Maybe this is very basic but I actually don't understand this error and how to fix it.

Could you please help me a bit? @mem48

Thanks!

And I also continuously meet this error

Scottish holidays are downloaded but not properly supported Warning: '/tmp/Rtmp0jrFBR/txc' already existsWarning: error 1 in extracting from zip file2023-11-02 17:31:03.968439 Importing TransXchange files, multicore |=============================================================================================================================================================================================================================================| 100%Error processing TransXChange file: /tmp/Rtmp0jrFBR/cambs_A2BR_1A2001A.xml.

I can't find the function transxchange_import_try in your function list....

This also happend to another function transxchange_export_try

UPDATE:

I've found that I can only seem to convert one file at a time, after which I need to reinstall the package UK2GTFS and then convert another one, otherwise I get the error above. Sometimes reinstalling doesn't work either, does anyone know how to fix this strange phenomenon please? My R and Rstudio environments are brand new.

The TXC 2.5 is not supported use the older version

@mem48 Hi thanks for your reply. I am still trying to solve this issue.

What do you mean older version? I think I am using the latest version of your github repo.

Do you mean my dataset can only be transformed by old version UK2GTFS? So how old it needed to be?

[mem48]

The TNDS is released with two versions v2.1 and v2.5 you need to download the v2.1 as v2.5 is not supported by UK2GTFS

@mem48 Thanks I understand.

But in their official website FTP server, they only provide TNDS2.5 version and I can't find any inforamtion about 2.1 with Google. Could you please kindly give me some tips?
