VelvetOptimiser

[paa6]

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.

I have also used velvetoptimiser recently but unable to understand result...can u please give me some hints how to start....I would really appreciate ur time...

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.

i have fixed this problem, thanks for your help.

[Votinhkiem90]

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.

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

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
