I am having issues with KEGG pathway xml files. In short, when I run
pathview() files are being downloaded, but they are not in xml format and cannot be parsed so I get the following error:
Start tag expected, '<' not found
I tried updating XML and KEGGgraph packages, but the issue is still there.
I am using R version 3.6.0 and Bioconductor 3.9.
Any suggestions would be much appreciated, sorry if I missed a solution to this problem being already posted elsewhere.
For reference, this is what what I get for an 'xml' file:
ENTRY hsa04622 Pathway NAME RIG-I-like receptor signaling pathway - Homo sapiens (human) DESCRIPTION Specific families of pattern recognition receptors are responsible for detecting viral pathogens and generating innate immune responses. Non-self RNA appearing in a cell as a result of intracellular viral replication is recognized by a family of cytosolic RNA helicases termed RIG-I-like receptors (RLRs). The RLR proteins include RIG-I, MDA5, and LGP2 and are expressed in both immune and nonimmune cells. Upon recognition of viral nucleic acids, RLRs recruit specific intracellular adaptor proteins to initiate signaling pathways that lead to the synthesis of type I interferon and other inflammatory cytokines, which are important for eliminating viruses.
