some problems when - Run main_test_seg.sh to test the resulting model for semantic segmentation.

Hello, I followed the - Run main_test_seg.sh to test the resulting model for semantic segmentation. in your README.md “，
I just want to use your open model ”seg_joint.caffemodel“　to test some pictures(I didn't train this caffemodel), then I got some troubles:
1:In the test_seg.prototxt,
layer {
name: "fc8_mat"
type: "MatWrite"
bottom: "fc8_interp"
mat_write_param {
prefix: "val/fc8/"
source: "list/val_id-py.txt"
strip: 0
period: 1
}
include: { phase: TEST }
}
What are stored in the folder "val/fc8"? the mat.type files ?　How do I get them?

2.In the pascal_val.yml, a txt files will be called: val_noisy_sigma30.txt. In this txt.file, the png.picture are the manual ground truth segmentations? the corresponding mat.file in this txt such as /val_noisy_sigma30/2007_000042.mat, /val_noisy_sigma30/2007_000175.mat and so on , How do I get them? The mat files in this folder are the same as in the val/fc8 folder?

Looking forward to your reply. Thanks.
