Error with bandpass_filter in MountainSort3

[cspurandare]

I am using a virtualBox Ubuntu 16.04 with 4 Gb ram and 20GB harddisk space allotted. I have been following the installation and compilation steps for MountainSort and did not encounter any errors until the step of sorting example data. The error says

|ms3.bandpass_filter| Error reading chunk

The entire message is appended below

Please let me know if any further information is needed. I have installed mountainlab-js but am a little lost about how the run the examples there. Thanks in advance, Chinmay

Perhaps you are running out of disk space in the /tmp directory?

Hi, Yes you were right, it was a space issue. I ran the example by generating data for 60 instead of 600 seconds and it worked well. Thanks

You're welcome, glad it worked.
