Dear UCSC Genome Browser team,

I am trying to lift coordinates from tomato (ITAG2.4) to tomato
(ITAG4.0) using liftover, but I cannot find the chain file.
Could you please provide a download link for this chain file or let me
know where I can obtain it ?
Thanks you very much for your help,
Best reagards,

Good Morning Chloé:

Can you help identify these assembly versions. I do not see these
identifier strings in any of the meta data for NCBI assemblies.
There are 57 assemblies of "Solanum lycopersicum":

https://genome.ucsc.edu/assemblySearch.html?q=%2BSolanum%20%2Blycopersicum;browser=mayExist

Perhaps you can identify the assemblies from that search result.
