Dear colleagues, I am having some trouble installing MAF datasets at our server. When I run "Extract MAF blocks given a set of genomic intervals", I got this error message: "Fatal Error: The MAF source specified (10_WAY_MULTIZ_hg19) appears to be invalid." Below is what I did by following the wiki page: http://wiki.galaxyproject.org/Admin/Datatypes/Add%20MAFs 1, download all mafs for hg19 from http://hgdownload.cse.ucsc.edu/goldenPath/hg19/multiz46way/maf/ 2, index them using "maf_build_index.py --species=hg19,panTro2, gorGor1,ponAbe2,papHam1,calJac1,tarSyr1,micMur1,otoGar1,rheMac2 $file". Our user requested primates only. 3, Here is my maf_index.loc file: == 10-way multiZ (hg19) 10_WAY_MULTIZ_hg19 hg19,panTro2,gorGor1,ponAbe2,papHam1,calJac1,tarSyr1,micMur1,otoGar1,rheMac2 hg19,panTro2,gorGor1,ponAbe2,papHam1,calJac1,tarSyr1,micMur1,otoGar1,rheMac2 /mnt/galaxyIndices/alignments/maf/chr1.maf,/mnt/galaxyIndices/alignments/m af/chr10.maf,/mnt/galaxyIndices/alignments/maf/chr11.maf,/mnt/galaxyIndices/alignments/maf/chr11_gl000202_random.maf,/mnt/galaxyIndices/ali gnments/maf/chr12.maf,/mnt/galaxyIndices/alignments/maf/chr13.maf,/mnt/galaxyIndices/alignments/maf/chr14.maf,/mnt/galaxyIndices/alignments /maf/chr15.maf,/mnt/galaxyIndices/alignments/maf/chr16.maf,/mnt/galaxyIndices/alignments/maf/chr17.maf,/mnt/galaxyIndices/alignments/maf/ch r17_ctg5_hap1.maf,/mnt/galaxyIndices/alignments/maf/chr17_gl000203_random.maf,/mnt/galaxyIndices/alignments/maf/chr17_gl000204_random.maf,/ mnt/galaxyIndices/alignments/maf/chr17_gl000205_random.maf,/mnt/galaxyIndices/alignments/maf/chr17_gl000206_random.maf,/mnt/galaxyIndices/a lignments/maf/chr18.maf,/mnt/galaxyIndices/alignments/maf/chr18_gl000207_random.maf,/mnt/galaxyIndices/alignments/maf/chr19.maf,/mnt/galaxy Indices/alignments/maf/chr19_gl000208_random.maf,/mnt/galaxyIndices/alignments/maf/chr19_gl000209_random.maf,/mnt/galaxyIndices/alignments/ maf/chr1_gl000191_random.maf,/mnt/galaxyIndices/alignments/maf/chr1_gl000192_random.maf,/mnt/galaxyIndices/alignments/maf/chr2.maf,/mnt/gal axyIndices/alignments/maf/chr20.maf,/mnt/galaxyIndices/alignments/maf/chr21.maf,/mnt/galaxyIndices/alignments/maf/chr21_gl000210_random.maf ,/mnt/galaxyIndices/alignments/maf/chr22.maf,/mnt/galaxyIndices/alignments/maf/chr3.maf,/mnt/galaxyIndices/alignments/maf/chr4.maf,/mnt/gal axyIndices/alignments/maf/chr4_ctg9_hap1.maf,/mnt/galaxyIndices/alignments/maf/chr4_gl000193_random.maf,/mnt/galaxyIndices/alignments/maf/c hr4_gl000194_random.maf,/mnt/galaxyIndices/alignments/maf/chr5.maf,/mnt/galaxyIndices/alignments/maf/chr6.maf,/mnt/galaxyIndices/alignments /maf/chr6_apd_hap1.maf,/mnt/galaxyIndices/alignments/maf/chr6_cox_hap2.maf,/mnt/galaxyIndices/alignments/maf/chr6_dbb_hap3.maf,/mnt/galaxyI ndices/alignments/maf/chr6_mann_hap4.maf,/mnt/galaxyIndices/alignments/maf/chr6_mcf_hap5.maf,/mnt/galaxyIndices/alignments/maf/chr6_qbl_hap 6.maf,/mnt/galaxyIndices/alignments/maf/chr6_ssto_hap7.maf,/mnt/galaxyIndices/alignments/maf/chr7.maf,/mnt/galaxyIndices/alignments/maf/chr 7_gl000195_random.maf,/mnt/galaxyIndices/alignments/maf/chr8.maf,/mnt/galaxyIndices/alignments/maf/chr8_gl000196_random.maf,/mnt/galaxyIndi ces/alignments/maf/chr8_gl000197_random.maf == Any hint on which step is wrong or missing is highly appreciate!
