UPDATE The problem seems to have disappeared when I used a larger sample of artefacts (40+ instead of a couple I used as a test group). So, if I understand it correctly, if the sample is too small, then the variability indices cannot be calculated, and the panel does not open. This is, however, just my best guess :) Cheers, Maciej

Dear users, Given the sample specific nature of the shape trends produced by the PCA, the original design of AGMT3-D did not allow to change the items included in a project after its creation. While this had an analytical reasoning concerning the universality of the results it also generated complicated workflows which are extremely demanding with regard to processing time and storage space - especially for larger projects. After several years working with the software and additional thought it was...

Hi everyone, I am a new user of this great program. So far, I only encountered one problem. After successfully processing my folder, creating a project and running the GPA and PCA, I am not able to open the "Assemblage variability" panel. To be exact, a window appears for a split second, and then disappears anytime I press the button. Has anyone else run into this problem? With best wishes and thanks in advance, Maciej Ehlert

Hi. So I'm not exactly sure what I did, but I made sure that all of the file names start with a letter and didn't have any dashes (-) or dots (.) in the filenames either and it started working for me. Hope that helps.

Hello, I have exactly the same problem. Thanks for your help. JL

Hello, I am using this program for the first time and have run into an issue. I was able to process the mesh's (25 total), but whenever I go to start a new project the first 7 process pretty quickly but then it gets hung up on 'Processing Files... 8 out of 25'. I left it running overnight and the next morning it was still stuck on processing 8 of 25. I downloaded meshlab and performed quadric edge collapse decimation as stated in another topic here, and I made all of the files start with a letter...

Hi Phoebe, I had a similar issue a while back. It might be that your meshes have too many vertices for the software to handle. A simple (if time-consuming) fix to this involves opening your meshes in meshlab and performing quadric edge collapse decimation (this can be found under filters>remeshing, simplification and reconstruction). This should reduce the number of vertices of each mesh without sacrificing detail. Just be sure to check you don't have any non-manifold edges or vertices afterwards...

Hi there, I'm a first time user and seem to be encountering problems with creating a project. Following the protocol in the user manual, i read the .wrl files to the program through the Process Folder function. After these were all processed, the .3dl and .xls files were placed in the folder alongside the .wrl files. I've now clicked "New Project" and selected GeoMorph files and then selected this folder containing all my files. The program created the "Morpho_Project" folder with all of the subfolders,...

Hi Gadi, Thanks for explaining that to me! I had wondered if that was the case, but was thrown by the surface area being just under half - it makes sense to me now. This is actually a very handy feature for isolating faces on bifacial artefacts - I haven't tried AGMT with any scans of cores yet but I'm eager to look into that now. I should also mention that I've noticed in the summary of raw results, under Inherent Atts, there is a column of 0's that appears under the 'Left Edge Section Irregularity'...

Hi Alex, Thank you for using the software and for posting your comment. The difference to which you refer stems from the different methods used to calculate these values in the different software. Specifically for the surface area, while Meshlab and other general 3D processing software measure the whole surface of an item (i.e. the sum of the areas of all faces in the mesh) AGMT3-D measures the "archaeological" surface area (i.e the 2D surface area of the projection of the item onto the bifacial...

Hi Gadi, I've just noticed that in v3.1 the volume and surface area measurements are quite different to those I get from Meshlab and CloudCompare - surface area in particular is significantly lower (usually under half) in AGMT, volume is also different but less so. It could be a problem on my side, although I don't think its a conversion issue, as the scans are in mm and as I understand it those measurements are in mm2 and mm3 by default in AGMT? Thanks in advance! Alex

Hello, I would like to ask what are the laptop requirments (RAM, CPU, graphics etc) in order to use the geomorph toolbox? Thank you, Tatiana

Dear Matt, I experienced the same problem (endless PCA calculation). The only solution that helped me was to turn off my antivirus program. I hope this helps you too. Best regards, Zakhar

I recently downloaded your software. Been able to process files into the correct format, but when it comes to starting a new project, the processing invariably stalls on the fifth file in the folder. This appears to be regardless of my removing the fifth file, the stalling is just passed onto the subsequent file. Thanks, Callum

I'm just trying out this tool and so far I'm impressed. Are there any plans to allow images and data to be stored in non-Matlab formats - like pngs and csvs?
-
Dear Matt, Let me start, again, by apologizing for the late reply. As I wrote to you last time, things always come up (unfortunately not always related to work or academia) . So, from reading your email I understand that my first guess was off. I have a few other thoughts - but as you suggested - I think the best idea would be that I will have a look at some of the files first. If it is ok with you, please send me the following files: YOUR_PROJECT_NAME-MorphoProject.mat - this file should be inside...

Dear Gadi, Many thanks for your replay and apologies for my late response. The file names I'm using all start with letters followed by numbers, e.g. 'AS142', should there be any space or hyphen between these characters possibly? I have reloaded a project using the landmarked files and ran the 'View Object' function and export options for four models, which gave me no issues. I then ran the GPA tool again (which worked fine), but again got stuck with the frozen 'Calculating principal component' loading...

Dear Matt, Thanks for your email, and sorry for the late reply, as I am currently the only one supporting AGMT3-D, replies sometimes get delayed. Concerning your issue, this is most definitely a bug and has nothing to do with your machine (which has excellent specs) . While the landmarking process is indeed somewhat slow (hopefully an issue that will be improved in the next version), the PCA shouldn't take more than a few minutes. From your email I get that you had no problems with the 'Process folder'...

Hello, I'm a first-time user and running into a potential problem I was hoping you'd be able help me with, regarding the PCA tool. I've uploaded 90 meshes, used a 50 x 50 grid (which took approx. 8 hours to landmark). After, I ran the GPA and PCA tools. Upon running the PCA tool, a loading bar saying "calculating principal components..." popped up, although after 11 hours of run-time, nothing happened. The GPA step was nearly instantaneous, so I wanted to know if this is potentially a bug or install...

Dear users, We are happy and proud to bring you the new version 3.1 of AGMT3-D with new and enchanced features including: • New project creation system. Creation of a new project now includes the measuring of inherent attributes for each artifact. These include metrics [max length, width, thickness, grid length, width and thickness, length to max grid width, length to max grid thickness, width and thickness at lower fifth, mid length, and upper fifth], volume, surface area, deviation form perfect...

Dear users, Following feedbacks we got from some of our users we have quickly released a new version which takes care of a serious bug that was discovered, as well as adds some new features. Major bug fix: In the landmarks’ positioning procedure, a bug which caused an error to occur in cases when the number of latitudes and the number of landmarks per latitude were unequal was fixed. Now any number can be assigned in each of the fields. The process folder procedure now saves a Microsoft Excel file...

Thanks to feedback I got from a user I figured users who don't have Matlab installed have no way to access the raw landmarks coordinates. This issue will be fixed in the next release of AGMT3D. In the meantime I'm releasing a simple tool for extracting the landmarks form the 3dl files and saving them as Excel. The tool is very simple, you just need to install it, run it, and select a folder contaitng 3dl files. the Excel files will be saved in new folder created in the folder containing the *.3dl...
