各位老师,我想用 phonopy计算的体系的声子谱,现在用cp2k得到了优化后的结构,然后利用导出后的cif文件在Ubuntu中计算振动,但是就报错:
“atomic mass of "Am" is not implemented in phonopy\\
mass tag can be used to set atomic masses”
于是我尝试手动在inp文件中添加原子质量然后又报错:Parsing crystal structure file "POSCAR" as in VASP format failed.(Calculator option is needed for parsing different crystal structure format.)Switched on phonopy-yaml mode."phonopy_disp-yaml" or "phonopy yaml" could not be found.
后面我尝试在命令行 添加原子质量phonopy -d --dim="2 2 2" -c POSCAR --mass="Am=243.0" --mass="C=12.01" --mass="H=1.008" --mass="N=14.01" --mass="O=16.00",或者把等号改为引号也尝试了又报错:could not convert string to float ‘Am=243.0’
这个问题可以怎么解决呢?
