... When I looked into the code for fun. of covplot, there is a fun. of getChrCov. Because I may want to get the chromosome coverage in table format. But when I run getChrCov, I got an error "no applicable method for 'slice_' applied to an object of class "c('Rle', 'Vector', 'Annotated')" ", because of ...

... Hi Gord, I think it should be $3-1 for the start position. My understanding is that BED format is 0-based for the second column (chromStart), while it is 1-based for the peak txt file from HOMER. I double checked the script of "pos2bed.pl", which is "my$start = \$line[2]-1;" to get start position. ...

... The reason for the fifth column are all set to 1 is that I think there is a bug in the Perl script of pos2bed.pl? Not matter you use "-5" option or not (-5 : Set 5th column to the value 1 instead of value in 6th column of pos file), the fifth column will be 1 always. ...

... Yes, it totally makes sense. But could you tell me how the distance to TSS is calculated (I will look up this too)? Because I see they are much different between homer and chipseeker, not only the number but also the sign (+/-). Please refer to the example at the bottom, the distance is 1312 VS -894 ...

... Also, I compared the annotation between ChIPseeker with another tool. The first few lines results are listed above (hope you can get the meaning for each column because of bad format. I don't know how to upload an image from my laptop). The Nearest.PromoterID are same between them. But the distance ...

... I think I should find a way to do this. I see ChIPseeker can accept a GRanges object. So, what I did is that I made a GRanges object from a data frame by makeGRangesFromDataFrame. Then, I used this as the input of ChIPseeker to do plots. Also, I used makeTxDbFromGFF to create TxDb from a GFF3 file. ...

... Hi Guangchuang, is there any way I can convert a TXT file (external annotated peak file) to a csAnno object? In other words, could ChIPseeker take external annotated peak file to do plots? Thanks a lot! BEST, Xiaofei ...

Comment: C: DESeq2 negative tab counts
...   I did send an email and cross my fingers to get response from them. Here is the command that I used for HOMER, it is very easy and just one-line command. getDifferentialPeaksReplicates.pl -t IP1_tagDir IP2_tagDir IP3_tagDir -i Inp1_tagDir/ Inp2_tagDir/ bInp3_tagDir/ -genome AGPv3 -gsize 2.2e9 & ...
