i would ask if you can help me in transform a cif file to input file of quantum espresso,the problem come after insert my parameters directly from cif,the software reported error in input file.
You can perhaps use the J-ICE online viewer. It can read .cif files and write QE input files. I don't know how much editing you need to do but it is worth a try:

Another way is to use BURAI** (a GUI of Quantum ESPRESSO) to transform a CIF file in a QuantumEspresso input
I would like to mention, all the method described above (especialy the Material Cloud www convertor) generate sub-optimal results, often leading to nonsense calculation time + handling more atoms than required.
The automatic methods described above abstract form the true lattice cantering = they generate up to 2-4 more atoms (in C,I,F centration) than necessary ..
The best method is to use it internal Quantum Espresso space group handling.
Folowing CIF sequence:
_symmetry_Int_Tables_number 15
_cell_length_a 12.8552
_cell_length_b 7.5003
_cell_length_c 31.9320
_cell_angle_alpha 90.0000
_cell_angle_beta 94.7850
_cell_angle_gamma 90.0000
Then direclty corresponds to following QE sequence:
space_group = 15
A = 12.8552
B = 7.5003
C = 31.9320
cosAB = 0
cosAC = -0.08341696
cosBC = 0
nat = 35
ntyp = 5
Atom position form CIF can than be directly given as:
