Hi Folks

I am running snpeff annotate some mouse mutations. One of my objetives is get the CDS length to determinate the annot ation of main transcript for each gene

i just used different databases in snpeff (GRCm38.75 , GRCm38.99 and GRCm39.10) but no information was found at the cds_length file

i used the following command

java -Xmx8g -jar snpEff.jar GRCm39.105 some.vcf > out.ann.vcf

nevertheless, the possision 13 (starting with 1 at the 1srt position) corresponding to CDS.pos / CDS.length is empty (i paste an example)

##INFO=<ID=ANN,Number=.,Type=String,Description="Functional annotations: 'Allele | Annotation | Annotation_Impact | Gene_Name | Gene_ID | Feature_Type | Feature_ID | Transcript_BioType | Rank | HGVS.c | HGVS.p |

##INFO=<ID=LOF,Number=.,Type=String,Description="Predicted loss of function effects for this variant. Format: 'Gene_Name | Gene_ID | Number_of_transcripts_in_gene | Percent_of_transcripts_affected'">

Could you tell me if i missing some flag running snpeff that makes that this information is missed?

thanks
