Due to the security settings on the clusterMana, when building a singularity container on Mana with the default settings it is possible that it will fail.  This is due to restrictions placed on a user home directory as far as who is granted access.  To work around this. user can try two things

1. Set the SINGULARITY_CACHEDIR to something other than one of your user/group/lab storage
2. Build the container is a directory that is not one of your user/group/lab storage locations

A recommendation for this is to use /tmp on the compute node for both.  Please make sure when creating your interactive sessions to request enough memory for your container  as /tmp uses memory on the computing node as no physical hard drives exist in the computing nodes.
