This is the first version of the SPACEBALL server.
The parameters are explained in our paper M. Chwastyk, M. Jaskolski and M. Cieplak, Structure-based thermodynamic and mechanical stability of plant PR-10 proteins with cavities, FEBS J. 281: 416-429 (2014) (see http://onlinelibrary.wiley.com/doi/10.1111/febs.12611/abstract)
To start the calculations you should provide adequate parameters. Fields marked by an asterisk (*) are entries that are required.
We can check your parameters before the start of the calculations, but it may take some time. If you wish that, just mark the box after the sentence "Please check my parameters".
We recommend not to change any of the default parameters except that the bigger number of rotations, the more accurate the result. However, 100 rotations is very accurate.
You should copy and paste the PDB file of your structure into the correct field. It is important to keep the standard PDB format.
You should give us your e-mail address, because the results of the calculations will be sent to this address.
If you see on the bottom of this page the message: "Captcha error! Refresh the webpage, please.", do not fill anything but just refresh the webpage.
You can contact us directly through the e-mail address given on the bottom of this webpage or by filling the contact field.
At the end of the questionnaire, please write down the captcha code from the bottom of the page just to confirm that you are a human.
