4 weeks ago This error was introduced after VG made slight changes in their JSON format output, representing nodes as strings instead of integers. There was a fix introduced. Did you try the latest version?
Hi, I am trying the graph_peak_caller in ATAC-seq mode as you suggested in #8 . I am following the pipeline in vg to construct the variation graph. I worked on the mouse genome, in which case 21 graphs for each chromosome was created. But I still expensed the same kinds of error as shown in #8, in the creating learn map step for most of the chromosomes (only Chr9, ChrX and ChrY work fine) :

But because I was using vg, I doubt that is the case, although I am not so sure about it. I wonder how you manage to find the disconnection in graph as you comment in #8 :
" For instance, node 133450827 has an edge going to 135833768, but these two nodes don't have any other edges to any nodes, so they are isolated together."
And also, I wonder if you any further suggestions about this error. Thank you so much!
Best, Peter
