snpEFF Database building error

I am using snpEFF for SNP annotation. I am building my own database. I added genome entry to snpEff's configuration. I'm building the database from a GFF file.

When I wrote out this command :

java -jar snpEff.jar build -gff -v Y55

I got this error:

Exception in thread "main" java.lang.UnsupportedClassVersionError: ca/mcgill/mcb/pcingola/snpEffect/commandLine/SnpEff : Unsupported major.minor version 51.0

Could not find the main class: ca.mcgill.mcb.pcingola.snpEffect.commandLine.SnpEff. Program will exit.

How do I fix this?

Thanks in advance! :)

Have a look at this thread on stackoverflow. In short, using a more recent version of java will probably fix this issue.

Thank you! I upgraded to a newer version of Java.

Now, I'm facing the following error.

Command:

java -Xmx2g /home/bioratcliff/SPRING-2014/Softwares/snpEff/snpEff.jar -c /home/bioratcliff/SPRING-2014/Softwares/snpEff/snpEff.config saccharomyces_cerevisiae -v LR1_sorted_snp.vcf > LR1_snpEFF.vcf
Error: Could not find or load main class .home.bioratcliff.SPRING-2014.Softwares.snpEff.snpEff.jar

It would seem that you need to set the class path.

I am also trying to build my database as the version I need is unavailable in snpEff.

edited snpEff.config:

# org genome, version org.7
org.7.genome : species
org.7.M.codonTable : Vertebrate_Mitochondrial

build database

>java -Xmx4g -jar snpEff.jar build -gtf22 -v org.7

I know there is no file called gene.gtf under ~/data/org.7/ but its ~/data/org.7/species.org.7.gtf/species.org.7.gtf . I have no idea why its pointing there and not on the real one.

Please guide. Thanks.

As mentioned here Building Snpeff Database, I even renamed my file to genes.gtf, but still same error.

I think its because I am using cygwin.

You forgot the -jar option:

java -Xmx4g -jar snpEff.jar ...
