unable to view spikes in qt-mountainview, ?sumit, mv

[ucnsgy]

Hi, I am having trouble seeing anything but auto-correlograms with qt-mountainview.
running qt-mountainview after synthesize_dataset.sh ms4_sort_bash.sh returns the error pasted at the bottom.

it looks like mv.mp mv.mv_compute_templates cannot retrieve from or save data to a temporary directory, which is not consistently called. additionally, qt-mountainview creates an odd directory tree in 001_ms4_bash_example folder beginning with " and matching my temporary directory name.

Unable to read chunk of templates in cluster detail view

my mountainlab.env file:
ML_TEMPORARY_DIRECTORY: /home/uskhan/anaconda3/envs/mountainlab/tmp
ML_PACKAGE_SEARCH_DIRECTORY: [default]
ML_ADDITIONAL_PACKAGE_SEARCH_DIRECTORIES: [default]
ML_ADDITIONAL_PRV_SEARCH_DIRECTORIES: [default]
ML_DATABASE_DIRECTORY: [default]

The following are the values actually being used:

Temporary directory: /home/uskhan/anaconda3/envs/mountainlab/tmp
Package search directories: /home/uskhan/anaconda3/envs/mountainlab/etc/mountainlab/packages:/home/uskhan/anaconda3/envs/mountainlab/lib/node_modules/mountainlab/system-packages
PRV search directories: /home/uskhan/anaconda3/envs/mountainlab/tmp
Database directory: /home/uskhan/anaconda3/envs/mountainlab/etc/mountainlab/database

My set-up is: mountainlab-js running on conda 4.7.12 (Python 3.6.9), qt-mountainview-0.1.4b1 compiled with qt 5.9.7, gcc 7.4.0 on Ubuntu 7.4.0-1ubuntu1~18.04.1. I was getting an identical error with a stock build of qt through conda. the new qt-mountainview build is linked correctly in my mountainlab packages/bin directories and references the correct ML_TEMPORARY_DIRECTORY, in my case /home/uskhan/anaconda3/envs/mountainlab/tmp

any help would be appreciated
