Tidypics 2.3.6 & ImageMagick Convert Command Issue

Dear Sir,

I am using Tidypics 2.3.6, with php 5.6 on Elgg version : Release - 2.3.10, Version - 2016092300

imagick (enabled)

 

and the extension = imagick.so is also loaded. 

I chose, ImageMagick as a better image library over GD, and on selection, I entered the following path -  

/usr/bin/convert   - but it fails !

However, if I use /usr/bin/ as the  ImageMagick  path the test is successful  as shown bellow.

ImageMagick

Tidypics needs to know the location of the ImageMagick executables if you have selected it as the image library. Your hosting service should be able to provide this to you. You can test if the location is correct below. If successful, it should display the version of ImageMagick installed on your server.

Version: ImageMagick 6.7.8-9 2016-06-16 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC Features: OpenMP

HOWEVER - Test on the Server shows different path as bellow: 

tribunal@web10:~$ which convert

/usr/bin/convert
This is the path for the extension

Here is the version :
tribunal@web10:~$ convert -v
Version: ImageMagick 6.7.8-9 2016-06-16 Q16 http://www.imagemagick.org

I am wondering, what is going on. Is the server setting incorrect, or there is something wrong with the Tidypics 2.3.6 ?
