Hello All, As I said before, I'm doing a lot of Miras by groups of 500 Miras. I have 17 lists with 500 manifest files each. I thougth that I didn't have any problem with the first 1500 Miras (with the first 3 lists). However, I couldn't assembly 28 contigs of list 1, 29 contigs of list 2, and 24 contigs of list 3. Mainly, I got these two error messages: 1) Thrown: void HashStatistics::loadHashStatisticsFile(string & hashstatfilename, uint8 basesperhash) 2) Thrown: void Assembly::dumpSomeStatistics() One of those manifest looks like this: project = comp4715_c0_seq1.mira job = est,denovo,accurate parameters = -GE:not=1 -NW:cmrnl=no -OUTPUT:output_result_html=yes readgroup = comp4715_c0_seq1._library_1 data = /home/ABTLUS/maria.villa/RNASeq_Pseudozyma/read_by_contig/comp4715_c0_seq1_Glicose_1_ACTTGA_merge_R1_001.fastq /home/ABTLUS/maria.villa/RNASeq_Pseudozyma/read_by_contig/comp4715_c0_seq1_Glicose_1_ACTTGA_merge_R2_001.fastq technology = solexa strain = pseudozyma segment_placement= ---> <--- readgroup = comp4715_c0_seq1._library_2 data = /home/ABTLUS/maria.villa/RNASeq_Pseudozyma/read_by_contig/comp4715_c0_seq1_Xilano_1_AGTCAA_merge_R1_001.fastq /home/ABTLUS/maria.villa/RNASeq_Pseudozyma/read_by_contig/comp4715_c0_seq1_Xilano_1_AGTCAA_merge_R2_001.fastq technology = solexa strain = pseudozyma segment_placement= ---> <--- readgroup = comp4715_c0_seq1._library_3 data = /home/ABTLUS/maria.villa/RNASeq_Pseudozyma/read_by_contig/comp4715_c0_seq1_Xilose_1_GGCTAC_merge_R1_001.fastq /home/ABTLUS/maria.villa/RNASeq_Pseudozyma/read_by_contig/comp4715_c0_seq1_Xilose_1_GGCTAC_merge_R2_001.fastq technology = solexa strain = pseudozyma segment_placement= ---> <--- -- Camila M.
