MBracket object (BRACES) does not render when single entity

Upon writing some MRV to load into MarvinSketch (5.7 on Windows 7 x64) it seems an MBracket object with the following signature does not render...

 

<MBracket id="o2" type="BRACES" orientation="SINGLE">

    <MPoint x="-1.0999995470046997" y="0.8799998760223389" />

    <MPoint x="0.6050000190734863" y="0.8799998760223389" />

    <MPoint x="0.6050000190734863" y="-1.5399999618530273" />

    <MPoint x="-1.0999995470046997" y="-1.5399999618530273" />

</MBracket>

 

 

If the type is changes to SQUARE or ROUND then the object will render. Is this a bug or is there something I am missing?

 

Thanks in advance.

Hi,

first of all, I am sorry for the late reply, we found that Marvin currently can not paint single brace type brackets, the single orientation is available for the square type bracket only in visualization.

We are about to implement this in a future version, how important is this feature for you?

Hi István,

 

Thanks for the reply and good to hear it will be resolved in the future. Single braces of this nature are quite important for us, as we allow single entities of this nature to be used in our system. Currently if the user hotlinks to MarvinSketch or saves to MRV from our system, this type of information  will be lost.

We are planning this feature in the 5.9 release.

Efi,

 

Thanks for the information.

Hi,

 

I have tested this using MarvinSketch 5.11.1 and there seems to be a problem with regards to direction of the bracket. I would expect the following...

 

    <MBracket type="BRACES" orientation="SINGLE" id="GrObj1" lineColor="#000000">

      <MPoint x="-11.2563" y="0.0479232" />

      <MPoint x="-11.1243" y="0.0479232" />

      <MPoint x="-11.1243" y="2.68792" />

      <MPoint x="-11.2563" y="2.68792" />

    </MBracket>

 

 

...to render left to right, i.e., "{". However, it renders right-to-left, i.e., "}". If you change the bracket type above to round or square it renders with the correct direction.

 

Can you please confirm whether this is a bug?

 

Thanks,

Nathan

Hi Nathan,

Yes, this is a bug, and the fix comes out in the next version.

Thank you for reporting,
