We can help .. here are the guidelines for common usage with the Tuxedo RNA-seq pipeline using a reference genome that is not-native to the Galaxy instance you happen to be working on:
1. The tuxedo pipeline will accept "reference annotation" in GTF or GFF3 format. GFF is not supported (will not contain the transcript/gene identifiers necessary to be useful). So you will be using this file: Malus_x_domestica.v1.0-primary.transcripts.gff3
2. The "reference genome" you need to be using is same consensus genomic backbone that the gff3 is based on (the chromosome identifiers and coordinates the transcripts/gene bounds are mapped to). This would be " Malus_x_domestica.v1.0"? You want the .fasta version of the genome loaded into Galaxy. As a "Custom Reference Genome".
3. You data for "Malus_x_domestica.v1.0.consensus2contigs.gff" and "apple_genome_contigs.nuc" maps back details about how the "reference annotation" was created from the source genomic contigs. Useful in case there is transcript assembly/gene assembly or splice variant question/discrepancy in a region and you wish to investigate (real or artifact/sequencing issue).
