annotatePeak error for some problem

Question

[Jones]

hello, everyone: when I use ChIPseeker to annotatePeak my chip-seq peaks, some error came. When I use this function, I encounter some issues and would like to seek advice. How can I resolve this problem? I would greatly appreciate your help. my code is showing here:

annot <- annotatePeakInBatch(M_K9me2_1, TxDb = txdb,tssRegion = c(-3000, 3000),annoDb="org.At.tair.db") 
In annotatePeak(M_K9me2_1, TxDb = txdb, tssRegion = c(-3000, 3000), :
Unknown ID type, gene annotation will not be added...

Do your identifiers match between your input file and your TxDB?
