Co-ordinates are mismatch, when i convert from .nii to jpeg

Hi. I have file in .nii format which consist of 706 images (0-705). from this file i want to convert image number 115 from to jpeg. i tried using `med2image -i ABD_LYMPH_002_mask.nii -o input.jpg -s 115` which successfully converts into jpeg format. But actually in this 115 image there are two nodules and i know there locations. I see and verify them using `MITK`. I unable to save image in jpeg using MITK so i tried `med2image`. But when i check nodules in converted jpeg image. nodules are in wrong coordinates. I am sending you .nii file (in zip fromat please unzip it, because attachment not supported in .nii format)
[ABD_LYMPH_002_mask.nii.zip](https://github.com/FNNDSC/med2image/files/1508775/ABD_LYMPH_002_mask.nii.zip)


and nodule locations are (183,193) and (323,186). and also sending you snapshot from MITK and of converted image using med2image. Checking co-ordinate of noudules in jpeg file i got nodule in location (185,317) and (325,322) which is wrong. Please see the issue. in attachment after ABD_LYMPH_002_mask.nii.zip there is jpeg image and other two images i got from MITK
