WebJul 12, 2024 · The featureCounts function in the Bioconductor Rsubread package does say it will accept a GFF file as input, so you might try that. However, the GFF file you are using is probably the wrong one. I believe you want medtr.R108_HM340.gnm1.ann1.85YW.gene_models_main.gff3.gz instead.

Did you know?
featureCounts looks for gene identifiers in GeneID column of a SAF annotation or by using GTF.attrType attribute in a GTF/GFF annotation. Then for each read featureCounts searches for meta-features that have at least one feature that overlaps with the read. A read might be found to overlap with more than one feature within the same meta-feature ...

Webcellranger在建库之前,有时候需要对GTF文件进行编辑修改。 比如为了后续在Seurat中使用正则匹配去除线粒体的基因,就需要修改原来GTF中的线粒体基因symbol名称,比如加上MT-或mt-前缀。 比如发现有些基因组存在一些重复的ID或者symbol的情况: 这种情况需要重命名其中一个基因symbol,也就是需要在GTF ...
