Hi DPDchrom team, Thank you for the powerful pipeline. I like the 3D model it created and I want to try your pipeline on my own data. However, It meet some question when I use the dpdchrom. Shows beneath ``` ./DPDchrom-master/dpdchrom B1.impute.csv 400000 0 Length of chromosome 1 1 480 Length of chromosome 2 4 384 Length of chromosome 3 5 372 Length of chromosome 4 10 319 Length of chromosome 5 6 366 Length of chromosome 6 9 303 Length of chromosome 7 12 292 Length of chromosome 8 17 230 Length of chromosome 9 2 447 Length of chromosome 10 8 316 Length of chromosome 11 3 392 Length of chromosome 12 7 355 Length of chromosome 13 13 294 Length of chromosome 14 15 252 Length of chromosome 15 16 237 Length of chromosome 16 X 414 Length of chromosome 17 18 219 Length of chromosome 18 14 305 Length of chromosome 19 11 297 Length of chromosome 20 19 146 Length of chromosome 21 Y 227 Program received signal SIGSEGV: Segmentation fault - invalid memory reference. Backtrace for this error: #0 0x7f0e80a7b51f in ??? #1 0x55ab9289b563 in ??? #2 0x55ab9289d0ad in ??? #3 0x55ab9289d54a in ??? #4 0x55ab9288d2fe in ??? #5 0x7f0e80a62d8f in ??? #6 0x7f0e80a62e3f in ??? #7 0x55ab9288d330 in ??? Segmentation fault ``` The example in the test file works well on my computer and I could visulize the mol2 result. I attached my own HiC csv file here. Could you please help me to find out the problem? Thanks. [B1.impute.csv](https://github.com/polly-code/DPDchrom/files/12362059/B1.impute.csv) Version of fortran compiler I used is GNU FORTUNE 9.4.0 and the OPENMPI 4.1.1(For some reason, the most up to date GNU FORTUNE could not complie the DPDchrom). Thanks again. Yuchen
