    Was your human genome FASTA indexed previously using a different version?

    Comment


    • #17
      Are you running it on a server or a PC, and do you have more than 3 Gb of memory available?

        I'm running on a PC using VMware wokstation and I allowed 4 gb.

          No. I indexed it with the same version.

            @FrankiB: Just want to confirm that you are using 64-bit unix of some kind?

            How much /tmp space have you allocated? Is adequate disk space allocated for the VM instance?

              Yes I'm using a 64-bit ansd 250 gb allocated for VM.

                Can you increase the RAM allocated to VM (6 or 8 GB) if possible and try? Allocating 4 GB to the VM may mean that a single process may not be able to get ~3.2 GB, which is what you need for an alignment job: http://bio-bwa.sourceforge.net/bwa.shtml#8

                  Yes I tried to allocated 7 gb and I got the same result...

                    Can you try to capture the standard error output to see if there is any additional useful information? The exact procedure would differ based on the shell you are using (e.g. http://www.cyberciti.biz/faq/redirec...err-to-stdout/)

                      I got about the same information:

                        Re-reading your previous posts I realized that in post #15 you said that index generated 2 files. That does not seem right. I have a feeling the indexing is the problem and did not work right the first time. Can you post a listing of index files for the genome? You may also want to try re-indexing.

                        There should be 5 index related files (*.amb, *.sa, *.bwt, *.ann, *.pac) besides the fasta file.

                          Sorry to have mistaken you, but I have generated the 5 files you are refering to.

                            Is it working now? You deleted a previous post that said that "aln" option was working but "mem" was not.

                              Yea. bwa aln is working well (it seems). Now I'm running bwa sampe to combine the *.sai files.

                                BWA.tar installation on windows

                                Hello Everyone!
                                I am looking a best software to align paired end reads from illumina MiSeq. Someone told me that I can use BWA-MEM or Subread to align paired end reads to the reference genome. I downloaded the BWA-MEM but I can't execute that because my computer has windows 32 bit version. the installation file has .tar.gz extension. Can anyone tell me how to open the execute the software on windows?
                                Many thanks!
                                MZB

                                  by seqadmin


                                  Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

                                  Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
