    How to fix this bold error?
    I'd say, by first fixing the real errors in your output. If you scan through your error log you will find that the execution of "velvetg" fails in all three cases. Thus, the problem is that VelvetOptimiser is not able to locate/execute the velvetg executable. As a consequence, there is of course no stats.txt as it is usually generated by velvetg.

    Possible solutions:
    1. Check the permissions of velvetg, maybe your Script is not allowed to run it.
    Code:
    ls -al `which velvetg`
    2. Find out, whether your velvetg executable is in the PATH (if not the above might not have worked either.)by running
    Code:
    velvetg
    If it doesn't run, you might want to reinstall velvet, correctly.

    Disclaimer: I have never used the VelvetOptimiser script and just try to help you find the source of the problem

          the simillar errors, how to fix it.

          Hi, Votinhkiem90:
          I'm glad that you fixed that errors.

          When I run VelvetOptimiser.pl, I meet the same errors as follows:
          Use of uninitialized value in numeric ne (!=) at /software/VelvetOptimiser-2.2.5/VelvetOptimiser.pl line 289.

          I checked botth Velveth and Velvetg, which works fine for this PATH.

          Could you give me some hints on how to fix this?

          Thank you very much and I appreciate your time.

            Yes, Possible you wrong for parameters cause this error. However You should check VelvetOptimiser install, and retype right parameters.
            Good luck
            p/s: can you sent the parameter that you run.

                  You have been run step by step with velvet with defaults parameters yet?
                  I think you should test with velvet before run with VelvetOpt. Now I don't use VelvetOptimiser along time ago, so im not sure how to fix this problem. but I guess this error from you cmd and parameter that you run.

                    I did try velvet before but now I am using velvetoptimiser. It's all that I am unable to understand results properly because there is no clear explanation for that..so can u give me some links for result analysis.

                      by seqadmin




                      Non-coding RNAs (ncRNAs) do not code for proteins but play important roles in numerous cellular processes including gene silencing, developmental pathways, and more. There are numerous types including microRNA (miRNA), long ncRNA (lncRNA), circular RNA (circRNA), and more. In this article, we discuss innovative ncRNA research and explore recent technological advancements that improve the study of ncRNAs.

                      Recent Developments in Metagenomics
                      by seqadmin





                      Metagenomics has improved the way researchers study microorganisms across diverse environments. Historically, studying microorganisms relied on culturing them in the lab, a method that limits the investigation of many species since most are unculturable1. Metagenomics overcomes these issues by allowing the study of microorganisms regardless of their ability to be cultured or the environments they inhabit. Over time, the field has evolved, especially with the advent...
